Generative Design - Week 5 - Introduction to optimization
1 like948 views
The document discusses an introduction to optimization in generative design. It defines elements of optimization including parameters, objectives, and constraints. It then explains how genetic algorithms can be used for optimization, describing the process as generating generations of solutions that get better over time through steps of initialization, selection, crossover and mutation. Finally, it notes optimization can be done in Grasshopper and promises a demo.

- 10. Generative Design September 10, 2019 Elements of optimization 1. Parameters – a set of variables that can be adjusted • discrete / categorical - whole number • continuous - decimal number • permutation / ordering - whole number sequence 2. Objectives - functions representing the goals of the problem • minimize value • maximize value 3. Constraints - functions representing conditions that make a valid solution 1. must be equal to a certain value 2. must be smaller than a certain value 3. must be greater than a certain value

- 28. Generative Design September 10, 2019 Genetic Algorithm A Genetic Algorithm creates “generations” of solutions in such a way that the solutions get better over time Steps: 1. Generate initial population of solutions 2. Rank solutions based on their performance in objectives and constraints 3. Generate next generation by applying elitism, crossover, and mutation to current generation 4. Repeat until termination criteria is met
