This transformation takes place via the generation of design alternatives. Digital morphogenesis techniques lend themselves to the task of producing design alternatives quicker and easily. In this paper, we introduce an interactive population-based model for evolving design alternatives. Our model enables designers to steer the trajectory of the evolutionary process. We use a population-based evolutionary approach that allows us to represent, evaluate and evolve design alternatives. We illustrate how the model is capable of generating a diverse space of alternatives, increasing the probability of finding unexpected designs. Finally we examine the results obtained, by defining measures of quality related to design intentions.

This model allows us to produce a vast array of different spatial topologies by evolving the boundaries of spatial units. This approach focuses on the formation of spatial patterns, where their characteristics emerge as consequence of the evolution of the system, rather than being prescribed by design. The experiment presented her investigates whether the composite CA is capable of generating aggregate spatial units to match the characteristics of specific spatial configurations.

Disentangling effects that are due purely to the result of policy and structural differences between schemes or jurisdictions to determine ‘what works’ can be difficult. Method We present a prototype policy exploration tool, ‘WorkSim’, built using an agent-based model and designed to enable workers’ compensation system managers to directly compare the effect of simulated policies on the performance of workers compensation systems constructed using agreed and transparent principles. Results The utility of the model is demonstrated through and case-study comparison of overall scheme performance metrics acro...

Consisting of multiple interleaved one dimensional CA, our model evolves the boundaries of spatial units in cross sectional diagrams. We investigate the efficacy of this approach by systematically varying initial conditions and transition rules. Simulation experiments show that the composite CA can generate aggregate spatial units to match the characteristics of specific spatial configurations, using a well-known architectural landmark as a benchmark. Significantly, spatial patterns emerge as a consequence of the evolution of the system, rather than from prescriptive design decisions.

However, the accelerated changes that many cities in the world have undergone during the past 40 years, have contributed to detract value from urbanity and sustainability as two fundamental aspects of civic life and compromising the role that the city used to play in the development of communal life. This article discusses the ways in which cities are being developed today focusing on the standardisation of urban production undertaken with consequential impact on the socio spatial structure. The main components of civic design are defined and the relationship with the concept of neighbourhood as a primary unit of urban intervention on multiple levels. Empirically, contemporary urban development and growth dynamics resulting from the paradigm shift that the city of Santiago, Chile has undergone since the second half of the 20th century, are critically discussed using Independencia and San Miguel as two key inner neighbourhoods. Finally, reflections on how to address the most relevant aspects of this accelerated socio spatial change through civic design are given as a way to recover the sense of urbanity and sustainability and then reincorporating them to the structure of society.

Complexity has many different, discipline specific definitions, such as complexity in physical systems (entropy), algorithmic measures of information complexity and the field of "complex systems". We apply a series of different complexity measures to three different evolutionary art datasets and look at the correlations between complexity and individual aesthetic judgement by the artist (in the case of two datasets) or the physically measured complexity of generative 3D forms. Our results show that the degree of correlation is different for each set and measure, indicating that there is no overall "better" measure. However, specific measures do perform well on individual datasets, indicating that careful choice can increase the value of using such measures. We then assess the value of complexity measures for the audience by undertaking a large-scale sur...

We conclude by discussing the value of direct measures in generative and evolutionary art, reinforcing recent findings from neuroimaging and psycho...

Approaches to using these methods for creative production typically focus either on optimisation or exploration. In this paper we introduce an evolutionary system for design that combines these two approaches, enabling users to explore landscapes of design alternatives using design-oriented measures of fitness, along with their own aesthetic preferences. We test our methods using a biologicallyinspired generative system capable of producing 3D objects that can be exported directly as 3D printing toolpath instructions. For the search stage of our system we combine the use of the CMA-ES algorithm for optimisation and linear interpolation between generated objects for feature exploration. We investigate the system’s capabilities by evolving highly fit artefacts and then combining them with aesthetically interesting ones. Keywords– Generative Design, Evolutionary Design, 3D Printing

In this paper we describe a biologically-inspired developmental model as the basis of a generative form-finding system. Using local interactions between cells in a two-dimensional environment, then capturing the state of the system at every time step, complex three-dimensional (3D) forms can be generated by the system. Unlike previous systems, our method is capable of directly producing 3D printable objects, eliminating intermediate transformations and manual manipulation often necessary to ensure the 3D form is printable. We devise fitness measures for optimising 3D printability and aesthetic complexity and use a Covariance Matrix Adaptation Evolutionary Strategies algorithm (CMA-ES) to find 3D forms that are both aesthetically interesting and physically printable using fused deposition modelling printing techniques. We investigate the system’s capabilities by evolving and 3D pr...
