Abstract

The present paper deals with the topological design of truss structures on the basis of stochastic algorithms. The recently proposed random cost method is applied to this problem and its performance is compared with the genetic algorithm and evolution strategy simulations. 1 Introduction Few powerful strategies for the search of optima in multimodal problems exist. Examples are the simulated annealing method [11] and the evolution strategy (ES) [13, 14] respectively the genetic algorithm (GA) [10]. An- other one, going under the name of random cost method (RC), was recently suggested by Berg [6, 7]. In [1] a noncanonical Monte Carlo procedure has been developed and applied to the simulation of random walks and random sur
