||Genetic Algorithms have emerged to be a very versatile optimization and search algorithmswbicb are most snitable for discrete optimization. This paper describes the fundamentals of a geneticalgorithm based computer software designed for structural optimization. At present the program iscapable to treat discrete size optimization of two and three dimensional structures made of 1-D elements.The main system integrates with a structural analysis program which uses the displacement method ofanalysis. The constraints involved are typically; nodal displacements, element stresses and stability. Theprogram incorporates code requirements. However, any preferred code restrictions can easily beincorporated. The program has a number of practical features including member linking and multipleloading. The penalty function and crossover techniques used in the GA are newly proposed and alsoexplained in the paper. The paper also discusses an illustrative example.
