summary Founded in 1995 LAB[au], laboratory for architecture and urbanism, links theoretic research LAB[a+u] to concrete works of conception and realisations LA.BAU. LAB[au] elaborates a “hyperdesign” investigating the implications of new technologies of communication and computation in spatiotemporal and social processes and their forms of representation as architecture and urbanism. The transposition of the hypertext model to architectural and urban concepts question the mutation of the spatial and semantic construct of space. The definition of architecture as a code is based on “glocal” systems according to the processes of computation and communication.

title Automation of Passive Solar Design System
source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary This research, focus on the automation of passive solar design system using computational method. The quantitative nature of passive solar design system makes the automation possible. The automation is done in stages, because implementing the passive solar design system is not an isolated process, but intertwined with the overall design process. The first phase of automation concentrates in conceptual stage, to avoid major deviations in later stages of the design. The conceptual stage use Eco-grammar (A preset Design guidelines for corresponding climate) and user inputs for initial form generation. The second stage of automation is done after the user finalize the model with respect to its position rotation and arrangements. In this stage manipulation of vertex, edges and faces of the forms were manipulated using genetic algorithm. The value of mutation or crossover done in genetic algorithm is suggested by knowledge engine (preloaded design knowledge). Until the form obtains or reach closer to the desired values of performance the loop between analysis and mutation, crossover will be continued. On the basis of analysis result further manipulations may change from the previous which is guided by the knowledge engine.

summary Taking as a starting point the hypotheses that the urban body is a self-adapted ecology made of material and non-material components (Bateson, 1972), relationships between elements are examined in an attempt to destabilize the static division of matter and idea and to inquire into those relationships that determine the structural coupling (Maturana, 2002) between body and environment, as well as the constitution of the body itself. Contemporary technology is used in order to trace these alterations and the urban body is examined as a network configuration. The importance of the methodology adopted by the current research lies in the fact that social and economic factors merge with spatial characteristics, allowing for a visualization and re-interpretation of the urban body mutations based on self-adapted reconfigurations and for a prediction of the structural alterations made possible through the reconfiguration of the synaptic forces between elements.

title An optimization method of the facility location by genetic algorithm
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary In planning of community-facilities, it is important to decide the facility location to provide the effective service for residents. The behavior of residents using the facility and the evaluation methods of the location have been studied. But, finding the optimum location is very hard in actual planning because the volume of calculation depends on the number of feasible locating points of facilities. To conquer the difficulty of searching the optimum location, we propose an optimization method using Genetic Algorithm. An alternative of location is expressed by a chromosome. Each chromosome consists of genes, and each gene expresses a located zone of the facility. We gave definitions of genetic procedures; crossing-over, mutation and selection. Alternatives of the facility location are generated by these genetic procedures like as life evolution. For each alternative, the behaviors of users are estimated by a spatial-interaction model, and the facilities that residents in each place choose are determined. The effectiveness of the location is measured by a total sum of distances between the facility and the user. After the confirmation of the effectiveness of our method by applying on ideal example problems, we applied it on the actual problem in Japanese town. By this method we could find the optimum location in about one-third time and effort as compared with the ordinal method.

title Posicionamiento de Volúmenes Arquitectónicos Mediante Algoritmos Evolucionistas (Positioning of Architectural Volumes by Means of Evolutionist Algorithms)
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 176-181
summary Configurational studies involve the groups of elements fulfilling restrictions defined by the designer in Architectural design. According to its necessities and intentions, the planner distributes the components of the group in a certain tridimensional way, establishing a composition. This operative procedure implies a classification system according to typologies that respond to a bigger system, and this in turn to another, until the whole is obtained. From the beginning the pattern should satisfy form restrictions, as well as dimensional and positional restrictions for each part that conforms the whole. Functional requirements are attended for each object satisfying relationships of connectivity and adjacency among them. In this work the parts are restricted by their relative position to a central element. Evolutionary Algorithms (EA) are used to solve this type of problem. Using evolutionary metaphors they originate concepts such as "genes", "chromosomes", "mutation", "crosses” and " population " (among other), which come closer to one of the solutions looked for by the designer, under combinatory stochastic methods. The most appropriate use of EA corresponds to problems of complexity NP-completeness (for example, problems of generation of cases of composition), allowing an efficient although not exhaustive analysis. Applying this technique to the generation of architectural volumes, some obtained results are exemplified.

title GenJam in Transition: from Genetic Jammer to Generative Jammer
source International Conference on Generative Art
summary GenJam, short for Genetic Jammer, is an evolutionary computation (EC) based software agent that models a jazz improviser. Recently GenJam has evolved away from its roots as an interactive genetic algorithm toward its current state as an autonomous generative system. GenJam has retained its chromosome-based representations and mappings, its intelligent selection, crossover and mutation operators, and its real-time interactive performance capabilities. However, it no longer needs any explicit representation of fitness, which arguably makes it no longer an EC system. This paper considers GenJam as a generative art system. Generative art produces “unique and non-repeatable events” that express a designer’s generating idea. The designer’s generating idea defines a species of events, represented in a genetic code. In music, these events could be individual notes, melodic phrases, even entire pieces. In GenJam the events are four-measure phrases, or “licks” in the jazz vernacular. The format for the genetic code, then, defines a species space from which unique individual events can be generated. Uniqueness is important in jazz because improvisation must be spontaneous and “new.” Hence, improvisation is tailor-made for the generative art paradigm, and in fact, one could argue that improvisation is, by definition, the purest example of generative art applied to music. In other words, generative music is improvisation, and GenJam is the Generative Jammer.

summary Contemporary explorations within the evolutionary computational domain have been heavily instrumental in exploring biological processes of adaptation, growth and mutation. On the other hand a plethora of designers owing to the increasing sophistication in computer aided design software are equally enthused by the formal aspects of biological organisms and are thus meticulously involved in form driven design developments. This focus on top-down appearance and surface condition based design development under the banner of organic architecture in essence contributes to the growing misuse of bio-inspired design and the inherent meaning associated with the terminology. HyperCell, a bio-inspired information design framework for real-time adaptive spatial components, is an ongoing research, at Hyperbody, TU Delft, which focuses on extrapolating bottom-up generative design and real-time interaction based adaptive spatial re-use logics by understanding processes of adaptation, multi-performance and self sustenance in natural systems. Evolutionary developmental biology is considered as a theoretical basis for this research.

title Representation, Realism and Computer Generated Architectural Animation
source Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 241-249
summary This paper documents a simple architectural form which, but for computer generated animation, has no ready alternative explanatory process for its complex generation. The subject is a column in the nave of the Sagrada Familia Church in Barcelona conceived by Gaudí at the beginning of this century without the contemporary opportunities for animated design exploration. The column is based on a set of counter-rotating mutually interfering profiles. As the column gains height, the profiles increase in interference with each other resulting in an increasingly fluted cross section, a tendency towards the Doric Order. For most, however, there is no easy access to a plausible explanation of the inherent rationale for the column. Animating the generation of the column reveals a unique and concealed sublimation of natural patterns of growth. Animation aids an understanding of the effect of the fourth dimension on design itself by releasing a meaning of time from an otherwise inanimate object. Here animation is used to decipher one aspect of the mystery of Gaudí's design while strengthening another: the source and conceptual power of Gaudí to anticipate this phenomenon. Rather than trivialising this design mystery, the explanatory role of the animation enriches comprehension of the formal concept of mutation through displacement or an evolutionary design paradigm. The paper discuss the implications of this ability to show transition, translation and dislocation without delving too deeply into how the animation was made, nor indeed the subject which, after all, requires animation to fully represent its less tangible qualities.

title Artificial Music Composer
source International Conference on Generative Art
summary Traditional Musical Computation Systems had to face the differences between the computational techniques and the characteristics of musical creation. Characteristics such as a high degree of subjectivity, a great irrational component, and a learning process based on the use of examples and environmental absorption, have made music difficult to be formalized through algorithmic methods or classical Artificial Intelligence methods such as Expert Systems. We propose the creation of a cybernetic model of a human composer in a primeval stage of human musical evolution, following a paradigm of cognitive complex models creation, based on the use of the human reference, not only in a static point of view but also considering its evolution through time. Therefore, the proposed system simulates musical creation in one of the first stages of musical evolution, whose main characteristics are the percussive and choral aspects. The system is based on Genetic Algorithms, whose genetic population is integrated by several tribes. This model carries out the task of musical composition, led by the user who expresses his/her musical taste assigning a punctuation to each tribe. The GA selects the worse tribes as individuals to be eliminated. In order to select those tribes which are going to be used as parents, a random function is used, having each tribe a probality proportional to its punctuation. The new tribe is produced by crossing the parent tribes in each individual. Afterwards, mutation takes place in the created individuals. The experiments carried out with this system have proved its functionality in the composition of rhythmic patterns. It is intended to enlarge the experiment's scope by communicating the system via Internet. This would enable its use by users of different musical cultures, taking into account that the system is user-friendly, since it requires no musical knowledge.

source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 219-224
summary It is presented a development of an exploratory experience about a hyper medial 4D and 5D space design workshop. The concept of 4D /5D space refers to a new representation order of the digital media that inserts space-time variables, where the subject’s action articulates the space. Directed by a group of professors, it was focused from different disciplines, and destined to a heterogeneous group of students. The work methodology recognizes and links the cyberspace, heterogenesis and morphogenesis concepts. As implications, it is observed the mutation of digital image-form creation, production, storage, interchange, interaction and social use, next to languages hybridation and representation systems. As conclusions, it is considered that the digital image-form is a random event, a result of an interrupted but not closed process where the creation vectors, procedures, direction variables and the subject prefiguration are the outstanding characteristics.

Cette évolution est la conséquence de l'évolution symétrique de l'espace urbain, de sa géométrie fondée sur le point de vue unique à une géométrie des points de vues multiples, du programme plannificateur à l'esquisse programmatique créant simultanément le programme et le projet. Nous expérimentons l'utilisation d'hyperdocuments avec un groupe d'étudiants de 3éme cycles sur le thème de l'enseignement du projet urbain.

summary The methodology presented here is grounded on the reconstruction of the urban body as a network configuration consisting of material and non-material components (Bateson, 1972). It is based on the assumption that if one can describe the rules that define the nodes and the connections of the network construction/urban body, as well as their attributes, then the differentiation on the relationships between elements, or even a shift from one value to another, would result in different network constructions, that would produce a time-based sequence of the self-adaptational and self-organizational reconfigurations occurring during the mutational procedure. The urban body is defined as the part of the urban tissue which distinguishes itself from the whole of the urban landscape, either because of constructed boundaries, or because of the strengthening of a specific attribute, which would result in a kind of an immaterial boundary, or, in other words the formation of an identity.

title Recapitulation in Generating Spatial Layouts
source Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 199-207
summary The noted 19th century biologist, Ernst Haeckel, put forward the idea that the growth (ontogenesis) of an organism recapitulated the history of its evolutionary development. While this idea is defunct within biology, the idea has been promoted in areas such as education (the idea of an education being the repetition of the civilizations before). In the research presented in this paper, recapitulation is used as a metaphor within computer-aided design as a way of grouping together different generations of spatial layouts. In most CAD programs, a spatial layout is represented as a series of objects (lines, or boundary representations) that stand in as walls. The relationships between spaces are not usually explicitly stated. A representation using Lindenmayer Systems (originally designed for the purpose of modelling plant morphology) is put forward as a way of representing the morphology of a spatial layout. The aim of this research is not just to describe an individual layout, but to find representations that link together lineages of development. This representation can be used in generative design as a way of creating more meaningful layouts which have particular characteristics. The use of genetic operators (mutation and crossover) is also considered, making this representation suitable for use with genetic algorithms.

summary This paper introduces a new experimental city generation, assembly and development platform, the urban mutations platform. We describe in detail a methodology for modeling urban systems and their dynamics, based on self-organization principles. The urban area is seen as an organism comprised of different “body parts”, the urban subunits. Upon creation of an initial 3D urban environment, it is possible to add to the subunits the so-called mutations, i.e. structural and functional components that can have beneficial or detrimental effects to the future city development. After addition of the mutations we allow the city to reorganize itself and observe possible changes in the urban configuration. These changes can be directly correlated to the added mutations and their urban qualities and allow us to probe the effect that different structural and functional elements have on the dynamic behaviour of the city, when placed at specific locations.

summary This paper presents the results from exploring the concept of ekphrastic expression as the foundation for a computation method to aid creative design. Ekphrasis or ekphrastic expression is the expression of a concept that is represented in one medium in another separate medium. The paper describes the concepts of ekphrastic expression and presents two implemented examples that demonstrate the method and produce new results. The first example involves the creation of new shapes through representing the shape designs in the evolutionary domain and introducing new operators within that domain beyond the standard evolutionary operators of crossover and mutation. The second example involves the creation of new genes to represent aspects of Frank Lloyd Wright's Prairie House style. This generates a space of genomes beyond those that were there at the commencement of the process. New designs that could not be directly produced in the original domain are generated.

summary The association of complexity and geometry was the starting point for an academic project at the chair of Computer Aided Design in Detmold. The students were asked to analyze a complex structure - taken from nature, art, technology or society - regarding the underlying geometrical rules and principles. The translation of these abstract geometric principles (logarithmic spiral, polyhedron, rotational solids, mesh-work, double helix…) into a three-dimensional structure was then realized in Rhinoceros. The 3D-modeling was followed by a transformation- and optimization-process of the initial shape by using the evolutionary principles of mutation and selection. The set-up for these variations followed predefined rules and principles for the manipulation of the original structure.

summary The ability to recognize properties and characteristics unforeseen in the early stage of design, namely shape emergence, is considered one of vital aspects of human visual perception in creative thinking. This study aims at developing a design model by using an extended theory of shape emergence, mutation shape emergence which we call. The first part of this paper describes the definition of mutational emergent shapes clearly. In the second part, possibility of discovering mutational emergent shapes will be explored through protocol analysis. On the basis of the results of these efforts, we will examine closely the cognitive mechanism to discover mutational emergent shapes. In the last stage, based on our results we propose a design model for understanding the cognitive process implications for training architects.
