title Using Genetic Algorithms for the Generation of New Designs Derived from Islamic Schools Plans
source Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 119; 431-442
summary Historic buildings are fruitful sources of architectural concepts which can be used to generate new designs characterized by authenticity and originality. Design computing methods have used varied techniques of knowledge representation in deriving new designs from architectural precedents such as: case-based design and genetic algorithms. This research has adopted genetic algorithms, a simulation of biological evolution to generate new plans from old ones belonging to the Islamic historical schools. The implemented method represents architectural knowledge in a simple schema (chromosome) and allows it to be modified easily using crossover operation to generate new plans with high fitness value. The research considered the fitness function as a measure of differences among the design characteristics of the sample of the Islamic schools. The results show the effectiveness of genetic algorithms in both analyzing past precedents and synthesizing their characteristics to produce new designs.

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.

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.

title La Arquitectura como Extensión Fenotípica Humana - Un Acercamiento Basado en Análisis Computacionales [Architecture as human phenotypic extension – An approach based on computational explorations]
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 56-60
summary The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

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.

title Adapting evolutionary computing for exploration in creative designing
source J.S. Gero and M.L. Maher (Eds.), Computational Models of Creative Design IV, Key Centre of Design Computing and Cognition, University of Sydney, Sydney, Australia, pp. 175-186
summary This paper introduces a modification to genetic algorithms which provides computational support to creative designing by adaptively exploring design structure spaces. This modification is based on the re-interpretation of the GA's crossover as a random sampling of interpolations and its replacement with the random sampling of direct phenotype-phenotype interpolation and phenotype-phenotype extrapolation. Examples of the process are presented

title Generalizing Ekphrastic Expression - A Foundation for a Computational Method to Aid Creative Design
source P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 345-354
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.

title Genetic Algorithms in Search, Optimization and Machine Learning
source Addison-Wesley, Reading, Massachusetts
summary David Goldberg's Genetic Algorithms in Search, Optimization and Machine Learning is by far the bestselling introduction to genetic algorithms. Goldberg is one of the preeminent researchers in the field--he has published over 100 research articles on genetic algorithms and is a student of John Holland, the father of genetic algorithms--and his deep understanding of the material shines through. The book contains a complete listing of a simple genetic algorithm in Pascal, which C programmers can easily understand. The book covers all of the important topics in the field, including crossover, mutation, classifier systems, and fitness scaling, giving a novice with a computer science background enough information to implement a genetic algorithm and describe genetic algorithms to a friend.

summary This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. That could be divided into four parts. First, is to set the population of GA operation. Second, is to choose crossover and mutation. Third, is to calculate the fitness function of each generation and to select the better gene arrangement. Fourth, is to reproduce, after evolution, we can establish Flooding Evacuation Path that more reflect really human action and choice when flood takes place. However we can apply GA to calculate different evacuation path in different time series. Final, we compare and establish real model of evacuation path model to choosing flooding evacuation path.

title Optimal Organization of Architectural Spaces Based on Genetic Algorithm

summary Genetic algorithms categorized as global search heuristics are search technique of seeking approximate or exact solutions for optimizing problems. Our generative tool named notchSpace starts from a population of randomly generated individuals which rationally subdivide architectural spaces with a low “fitness”. During generations’ evolution, the population is recombined, modified and mutated at a low rate to form new modes of building spatial subdivision; a new population is used in the next iteration. NotchSpace works up a research platform to evolve architectural spaces, and it explores the thinking of translation from computer algorithms to the field of architecture.

title Towards Urban Densification Using Shape Grammar to Develop Components for Retrofitting Street Design
source Ji-Hyun Lee (Eds.) "Hello, Culture!"  [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, p. 505
summary Cities will have to become denser to accommodate expanding urban populations, creating a challenge for urban mobility. Existing urban infrastructure must be retrofitted to promote the use of collective and active modes of transportation. This article presents a prescriptive grammar, for retrofitting urban street design in the context of densification, based on patterns extracted from current guides and manuals. This prescriptive grammar is a crossover between concepts of shape grammar and pattern language, joining generative capabilities of geometric shape grammars with descriptive and prescriptive approaches commonly referred to as design patterns. An example is presented to illustrate its application.

summary Crossing over a variety of digital and physical media, creation and representation of an architectural design process can influence perception, comprehension and conception of spatial volumes within both physical and virtual environments. These tools then transform and translate the design process from virtual to tangible portrayal of architectural design and vice versa. Artists and designers pushed media to new interpretations of the media themselves and with that of their artwork. Using these potentials and translate them by employing current technologies we embarked to new understanding and communication of architectural gestalt, form finding and design process. Interchanging and merging design environments from reality to virtuality to an extent that the boundaries of each one are dismantled, both realms can be used together in an overall process that leads to alternative form findings and resulting designs.

title 3D Crossover: exploring objets digitalisé
source International Journal of Architectural Computing vol. 2 - no. 4, 476-490
summary By merging a range of digital and physical media, the architectural design process is enriched by different perceptions, comprehensions and conceptions of spatial volumes within both physical and virtual environments. The use of digital media often confines the design process to only the digital realm; in this class, students moved fluidly back and forth from digital to physical using digital tools in unorthodox ways. These different media transformed the design process from a tangible portrayal of architectural design to a virtual portrayal, and vice versa. With this interchanging and crossing over of design environments from reality to virtuality the limits of each one are dismantled, both realms can be brought together in an overall process that led to alternative form findings and resulting designs. This work lies in the tradition of artists who push media to explore new interpretations both of the media themselves and of their artwork.

title Closing the Gap: The e4d Design Series and the Mediation of Digital Design Skills
source Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 204-211
summary The e4d design series is looking for an innovative use of digital technology in architectural education to overcome the gap between design development and the acquisition of digital skills. Digital design approaches include multimedia technology, the crossover of analogue and digital techniques, rapid-prototyping, visualization, and the presentation in artistic movies. Over the past two years a problem- based design approach was developed, which enabled students to learn digital and architectural skills simultaneously and efficiently. The educational concept consisted generally of four steps, which, though independent of each other, are determined by questions of the ongoing design process. The first step consists of an abstract or subjective research phase; in the second step the findings are transferred into dynamic spatial structures. Later, the detected qualities are used to develop a given building program. Finally, the different traces are connected, when site-specific parameters are blended with the design traces. This paper examines and evaluates textual and visual design approaches, the precise use of different kinds of media for the projects’ visualization, and the way architectural projects can be discussed; in addition, a competent monitoring of the process and outcome of innovative and efficient design strategies in architectural and pedagogical aspect is included.

summary For years, lack of public participation has affected the quality of design and planning. The developing cities constantly face the anti-development sentiments on the part of local residents because of controversial decision of development. Rapid development of information technology provides us with a chance to mend the delay of communication with the public in design procedure. It makes it possible to get the resident's reaction to a new project. Unlike a purely CAD-based environment, computer application to urban design is based on a blend of computer-aided design, spatial information system, and interactive multimedia. It is the combination of geometric, geographic, and annotated information and the need of data integration by collaboration and meanwhile it provides opportunities of participation. Due to the position at the crossover of architecture, landscape architecture, and planning, urban design attempts to control the proceeding in both design improvisations and socio-economic policies. In this proceeding, public participation plays an important role in exchanging opinions with the masses. In the situation of participation in China, we can synthesize some useful methods of public participation in the urban design by means of computer simulation, computer communication, and diverse software and tools, etc.
