summary	This paper posits a design approach that integrates multi-agent generative algorithms and structural topology optimisation to design intricate, structurally efficient forms. The research proposes a connection between two dichotomous principles: architectural complexity and structural efficiency. Both multi-agent algorithms and Bi-directional evolutionary structural optimisation (BESO) (Huang and Xie 2010), are emerging techniques that have significant potential in the design of form and structure.This research proposes a structural behaviour feedback loop through encoding BESO structural rules within the logic of multi-agent algorithms. This hybridisation of topology optimisation and swarm intelligence, described here as SwarmBESO, is demonstrated through two simple structural models. The paper concludes by speculating on the potential of this approach for the design of intricate, complex structures and their potential realisation through additive manufacturing.

summary	Real time walkthrough is a valuable resource, especially in the early stages of the design process. Assessing how shadows and reflections behave enables architects to make better choices regarding materials, geometry and lighting. Traditional methods do not offer daylight simulations in real time, whereas interactive visualization requires large computational resources to allow an evaluation of behavior of light in architectural space. This project researched virtual environments that permit the real - time generation of interactive scenes that simulate natural light algorithms modeled. The goal of this is to meet the needs of architects when evaluating the changes of a dynamic and synchronous project.

summary	A new housing complex on the Campus of the University of Patras, Greece, is expected to serve as a test-bed for experimentation with a parametric design process that integrates significant climatic data. To optimize the environmental performance of the proposed housing complex a parametric design algorithm has been developed. The algorithm links the weather data in the area with the site topography and the basic geometric features of the buildings on the site. To explore the interaction of the building features with the prevailing winds in the area and the solar exposure throughout the year various software applications, including computational fluid dynamics (CFD) simulations, have been utilized. The inclusion of wind data in the algorithm renders it particularly effective. The developed parametric process has been useful during the early design phase when studies on various patterns for arranging the buildings on the site were conducted. The parametric process has facilitated the configuration of the typical building block as well.

summary	Algorithm Aided Architectural Design (AAAD) is considered a second paradigm shift in the Architectural design process after the first one of bridging the conventional design process to the digital realm of design. This paper is divided into two parts, the first part comprehends the Algorithmic Architecture approach of from the point of view of tools, techniques, theories and practice in order to find the Algotecture theories on the map of Digital Architecture. Then, the paper exemplifies an application on Algorithmic Architecture. FALLINGWATER TOOLBOX VERSION 1.0 is a computational design demo tool for architects to aid in the house schematic design phase according to an analytical study of Frank Lloyd Wright's basic design rules and spatial program of his masterpiece; FallingWater House, (Edgar J. Kaufmann family house 1939). These rules have been transferred to algorithms and code thereafter. At a preceding stage, the Graphical User Interface (GUI) was developed using MAXScript 9.0. Using the FALLINGWATER TOOLBOX, infinite number of house prototypes can be generated within few minutes. Although, the FWT is based on a hypothetical design problem of producing prototype alternatives for a new house with the same identity of the Edgar Kaufmann House, the concept of the tool can be applied on a wider range of problems. It may help generating prototype alternative solutions for residential compounds design according to the required constraints.

title	Quantum architecture: an indeterministic and interactive computational design system
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 619-628
doi	https://doi.org/10.52842/conf.caadria.2010.619
summary	The evolution of computational design technique from mere substitution of hand drawing to customised design algorithms exhibiting a certain degree of intelligence, naturally opens up a new research frontier that studies the relationship between designers and customized design algorithms. Most of current customised architecture design algorithm adopts a deterministic paradigm to raise their design questions, that is to say, given the explicit rules and parameters, only one solution is allowed at each discrete computation step. Due to this deterministic nature, an intuitive and efficient communication between design algorithm and designer is hard to achieve, as there is almost no space for designer to step into the running generative process. This lack of progressive communication channels and the inefficiency of translating perceptual judgment into computer language directly results in the unconscious rejection of non-parameterisable design factors like intuition, aesthetic judgment and associational reasoning that are essential to any design activity. This paper introduces the quantum design paradigm as alternative computation paradigm for constructing an interactive and intuitive design system. An algorithm prototype, probability field, will be introduced to illustrate the logic and possible application of the proposed quantum design paradigm.

title	A framework to integrate generative design techniques for enhancing design automation
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 127-136
doi	https://doi.org/10.52842/conf.caadria.2010.127
summary	This paper presents and demonstrates a computational framework that facilitates the integration of different generative design techniques to enhance design automation. The framework is based on the evaluation and comparison of four main generative design algorithms. Effectiveness of the framework is demonstrated through an example scenario. Compared to most existing generative design systems that are based on one of the techniques, which often bias the generative design process in a certain direction, new generative design systems by applying the proposed framework will provide the trigger at each stage as demonstrated in the example scenario for the designer to perceive the emergent designs from different viewpoints. This advantage will enhance design generation and automation by assisting the designer in making more informed decisions in understanding and selecting the suitable generative techniques for different design needs.

summary	This paper explores the use of subdivision algorithms for the production of three-dimensional ornament. In a first step, this paper presents modifications to the Catmull Clark and Doo Sabin processes’ weighting schemes. In a second step, it proposes how these modified processes can be applied specifically to the generation of ornament. It presents methods for specifying weights using parameters both intrinsic and extrinsic to the mesh. Strategies for working with both very uniform and more differentiated input meshes are considered.

title	Computation against design? Toward a new logicocentrism in architecture

doi	https://doi.org/10.52842/conf.acadia.2010.049
summary	The purpose of this paper is to make apparent critical and theoretical aspects of the instrumentation of new technologies inside architectural processes. After twenty five years of “Choral Work” between architecture and post-structuralist philosophy superimposed together inside architectural processes, we now face a new technological era which seems to provide a new figure of authority by replacing logocentrism to mathematical logicocentrism. Everywhere, the “insemination” of computer by biogenetic algorithms and codification processes transform matter into a zoocentric paradigmatic system, which is supposed, by its internal “modulation,” to extend our potential of social dynamics into space. The goal of our demonstration will then be to examine new technical and theoretical strategies, in a way that the positivistic structure of computation can avoid a totalizing effect (that leading architecture under technological domination), but open up to an un-programmable (emergent) future far above “weaving” and calculated design.

summary	Ubiquitous computing enables us to decipher the biosphere’s anthropogenic dimension, what we call the Urbansphere (Pasquero and Poletto 2020). This machinic perspective unveils a new postanthropocentric reality, where the impact of artificial systems on the natural biosphere is indeed global, but their agency is no longer entirely human. This paper explores a protocol to design the Urbansphere, or what we may call the urbanization of the nonhuman, titled DeepGreen. With the development of DeepGreen, we are testing the potential to bring the interdependence of digital and biological intelligence to the core of architectural and urban design research. This is achieved by developing a new biocomputational design workflow that enables the pairing of what is algorithmically drawn with what is biologically grown (Pasquero and Poletto 2016). In other words, and more in detail, the paper will illustrate how generative adversarial network (GAN) algorithms (Radford, Metz, and Soumith 2015) can be trained to “behave” like a Physarum polycephalum, a unicellular organism endowed with surprising computational abilities and self-organizing behaviors that have made it popular among scientist and engineers alike (Adamatzky 2010) (Fig. 1). The trained GAN_Physarum is deployed as an urban design technique to test the potential of polycephalum intelligence in solving problems of urban remetabolization and in computing scenarios of urban morphogenesis within a nonhuman conceptual framework.

summary	This research asks the question of how the design knowledge production mechanism is processed differentiates digital design actors from each other in the social media/professional and academic fields of architecture. Due to the broad nature of the research question, the study focuses on academia and academia-related media through prominent architect-authors and subject titles in the literature. Bourdieu’s concept of capital is introduced, in which cultural and symbolic capital are considered part of the production values of digital design actors. Digital design actors use image-based social media tools such as Instagram effectively. The paper uses two methods: the first is a bibliographical analysis of author-texts, and the second is a social network analysis. By employing the keyword-based search from the Web of Science database, this study has managed to extract papers with full records (citations, keywords, and abstracts), with the journal Architectural Design having most publications. Considering that both academicians and professionals contribute to publications in Architectural Design, we selected all its publications between 2010-2020 for bibliometric analysis. These analysis techniques include the bibliometric network analyses and social network analysis with the focus on visualizing the algorithms and statistical calculations of well-established metrics. The research reveals the most critical nodes of the bibliometric network by calculating the appropriate central metrics. The network formed by the selected Instagram accounts of digital design actors are shown to be a small-scale network group, while the hashtags of digital design concepts are more numerous than the digital design actors.

summary	This paper proposes a solution to the problem of digital image segmentation based on clustering techniques. K - means and fuzzy k - means are clustering algorithms detailed within this study. We propose novel modifications to k - means and fuzzy k - means algorithms to vary objective functions and to use color difference as a distance measure. These new algorithms are guaranteed to obtain the same results as the originals while considerably reducing the execution time. Pixel growing is used to obtain connected structures in the results of clustering algorithms.

summary	The paper addresses the design of large roof structures for semi outdoor spaces through an investigation of a type of performance-oriented design, which aims at integrating performance evaluations in the early stages of the design process. Particularly, aiming at improving daylight and thermal comfort under large structures, the paper focuses on the exploration of passive solar strategies to reduce the need for imported energies. Referring to this context, the potential of parametric modeling is investigated with respect to performance-oriented design and a method, denoted ParaGen, is presented, based on the integration of parametric modeling and genetic algorithms. The potentials of the method are shown by discussing a case study, the roof SolSt. The design process of SolSt is based on parametric variations of its curvature, the density of its modules and the geometry of its cladding and explored based on the daylight and solar exposure of the covered spaces.

summary	The use of StyleGAN algorithms proposes a novel approach in the investigation of architectural images. Even though graphical outcomes produced by StyleGAN algorithms are far from being architectural spaces, they might become a starting point in the creative process of architectural projects. By creating a database of specific categories of architectural images located in certain contexts, significant findings might emerge regarding their categorization in accordance to the style of a culture. This research analyzes the architectural images that result from implementing StyleGAN algorithms in a database of images of Chilean houses built between the years 2010 and 2020 and selected as finalist of the Â´Project of the YearÂ´ from international viewers and curators of the most viewed architectural website of the world. Our findings suggest that Chilean houses have two distinctive elements strongly influenced by human bias: the proportion of voids in the architectural-like generative volume and the integration of vegetation or landscape.

summary	Robotic additive manufacturing has garnered significant research and development interest due to its transformative potential in architecture, engineering, and construction as a cost-effective, material-efficient, and energy-saving fabrication method. However, despite its potential, conventional approaches heavily depend on meticulously optimized work environments, as robotic arms possess limited information regarding their immediate surroundings (Bechthold, 2010; Bechthold & King, 2013). Furthermore, such approaches are often restricted to planar build surfaces and slicing algorithms due to computational and physical practicality, which consequently limits the feasibility of robotic solutions in scenarios involving complex geometries and materials. Building on previous work (Çapunaman et al., 2022), this research investigates conformal 3D printing of clay using a 6 degrees-of-freedom robot arm and a vision-based sensing framework on parametrically reconfigurable tensile hyperbolic paraboloid (hypar) formwork. In this paper, we present the implementation details of the formwork system, share findings from preliminary testing of the proposed workflow, and demonstrate application feasibility through a design exercise that aims to fabricate unique components for a poly-hypar surface structure. The formwork system also offers parametric control over generating complex, non-planar tensile surfaces to be printed on. Within the scope of this workflow, the vision-based sensing framework is employed to generate a digital twin informing iterative tuning of the formwork geometry and conformal toolpath planning on scanned geometries. Additionally, we utilized the augmented fabrication framework to observe and analyze deformations in the printed clay body that occurs during air drying. The proposed workflow, in conjunction with the vision-based sensing framework and the reconfigurable formwork, aims to minimize time and material waste in custom formwork fabrication and printing support materials for complex geometric panels and shell structures.
