File Information
Description

Here a specific generative algorithm, known as cellular division or an L-system, is used as an abstraction layer between a genetic algorithm genotype and phenotype. This approach is applied to the design of a structural truss. For each given truss topology, the optimal size problem is solved using sequential linear programming based on a finite element analysis model. Advantages include the ability to explore trusses with a variety of dimensions using a fixed-dimension genotype, and the automatic generation of designs that satisfy truss stability requirements.

The code is supplementary material for the following publication:

James T. Allison, Ashish Khetan, Danny Lohan. 'Managing Variable-Dimension Structural Optimization Problems using Generative Algorithms.' In the Proceedings of the 10th World Congress on Structural and Multidisciplinary Optimization. May 19–May 24 2013.
