In the recent literature, a description of the conditions under which an algorithm can be expected to be successful or fail is not often included in the studies. Because of this, in this work we compare the performance, in terms of precision and stability, of five heuristic algorithms in order to obtain valid statistical results. The problem instance we have used to do the comparison is the optimal weight design of a set of two dimensional steel frames. The new Bacterial Foraging Optimization Algorithm (BFOA), the Bees algorithm (BA), the Par- ticle Swarm Optimization (PSO),the Genetic algorithm (GA) and the Simulated Annealing Algorithm (SAA) were tested. This work also provides an initial assessment in terms of the success rate and quality of the solution.
