Evolutionary Principles applied to Problem Solving

Evolutionary Principles applied to Problem Solving
There is nothing particularly new about Evolutionary Solvers or Genetic Algorithms. The first references to this field of computation stem from the early 60's when Lawrence J. Fogel published the landmark paper "On the Organization of Intellect" which sparked the first endeavours into evolutionary computing. The early 70's witnessed further forays with seminal work produced by -among others- Ingo Rechenberg and John Henry Holland. The term "Evolutionary Computing" may very well be widely known at this point in time, but they are still very much a programmers tool. Pros and Cons Before we dive into the subject matter too deeply though I feel it is important to highlight some of the (dis)advantages of this particular type of solver, just so you know what to expect. Firstly; Evolutionary Algorithms are slow. Secondly, Evolutionary Algorithms do not guarantee a solution. Evolutionary Algorithms are also quite forgiving.

Geometrical BIM Tools Development - Geometry Gym Evolutionary Solvers: Fitness Functions « I Eat Bugs For Breakfast This is the second post in a series on Evolutionary Solvers. In biological evolution, the quality known as “Fitness” is actually something of a stumbling block. Usually it is very difficult to say exactly what it means to be fit. A fit individual is on average able to produce more offspring than an unfit one, so we could say that fitness equals the number of genetic children. At least in Evolutionary Computation, fitness is a very easy concept. Let’s have a look at the fitness landscape again and let’s imagine it represents a model that seeks to encase an object in a minimum volume bounding-box. When we need to mill or 3D-print a shape, it is often a good idea to rotate it until it requires the least amount of material to be used during manufacturing. When we pick two rotational angles at random, we end up somewhere on the fitness landscape. Every individual tries to maximize its own fitness, as high fitness is rewarded by the solver. This fitness landscape has two kinds of solutions.

Call for Galapagos submissions Dear users, in a couple of weeks I'm giving a lecture at the AAG10 conference and I'll be talking about Galapagos. Instead of a set of hypothetical scenarios I'd much prefer to show actual cases where Galapagos is used to solve a problem. Of course I realise that in the current state Galapagos leaves much to be desired. Wishes have been pouring in since it was first included and I have every intention of working on these in the upcoming week(s). I talk about some of the behind-the-scenes algorithms that drive Galapagos in this post. Goodwill, David David Rutten david@mcneel.com Poprad, Slovakia Tags: Galapagos ▶ Reply to This BIG | Bjarke Ingels Group Grasshopper Incubadora Social ITESM-Bancomer -Opportunity for social development- This refurbishment intends to offer a new quality-based, morphological-exploration for a social entrepreneurship incubator in a low-income area in León, Guanajuato, México. The initiative of these social interventions is lead by two main institutions: Tecnológico de Monterrey (one of the best private universities in México) and Bancomer (one of the main banks of the country). Having as canvas a prototypical house of the area, but being an innovative project for the community, the refurbishment intended to make a statement through an evident translation of the spatial concept to design: an envelope able to break the typological sequence of the area, still being inviting rather than aggressive; creating an expressive main façade within an open public space. As one of the core principles of the studio, sustainability is approached in this project through solar control strategies and passive ventilation.

Organization is the key. Seeking to help, find solutions and take care of the others in much order as possible… Hence the city has several layers as molding parameters… let them promote quality in public spaces, where people must be protagonist of their own decisions by been aware to change when ever is necessary… Istanbul Disaster Prevention and Education Centre, render courtesy Shine Architecture The 9,000 square meter pedestrian-oriented complex, sited adjacent to multiuse facilities (commercial-administrative-tourism-among others) of Istanbul, aims to counter the current privatized airport-urban developments in Bakirköy district by creating a contemporary porous urban space, inviting and open to the public from every side.

Media Park Ciudad Juarez \ SHINE Architecture Shelter for Juarez The spatial topology intends to generate a dichotomy in use: a sheltered space with inner uses and an upper skin working as open transversal spaces in a city in vicissitude. Media Park Ciudad Juarez, sketch courtesy SHINE Architecture The morphology was given by bioclimatic studies having as outcome a series of passive strategies for the extreme and complex weather of Ciudad Juarez. Media Park Ciudad Juarez, drawing courtesy SHINE Architecture Furthermore the over/open park serves as a lung for the city, avoiding the greenhouse effect , providing with specific plants evapotranspiration for humidity control in the area, also having thermal mass increase in the roof for inner thermal control, thus keeping the space in the right comfort zone. The inner void contains a complex volumetric program, “floating” between spaces emerging from the basement and reaching the upper skin. + Project facts + All images and drawings courtesy SHINE Architecture Tags: Fluid form, Mexico
