Abstract

This paper presents an enhanced genetic algorithm with a randomized line search technique to improve the convergence and accuracy ratio. The presented technique is the simple one-dimensional search in which design variable axes are selected randomly as the search direction. The presented algorithms are applied to the discrete sectional optimization problems to achieve the minimum structural weight and the minimum structural cost of the 3-story and 5-story steel structural plane frames. The numerical results obtained by the presented algorithm are compared with those obtained by the conventional genetic algorithm to check the effectiveness.
