A solution method for optimal cost problem of welded beam by using genetic algorithms

In this paper, we formulate an optimal cost design problem of a constrained allowable normal stress, shearing stress, the dimension of a welded beam and the bar deflection as a nonlinear programming (NP) problem and solve it directly by keeping the nonlinear constraint based on genetic algorithms (GA). We discuss the efficency of the propose method.
