In this paper, we formulate an optimal weight design (OWD) problem of elastic frame structure for a constrained relative story displacement as a statically indeterminate structure problem and solve it directly by keeping the constraints based on an improved genetic algorithm (iGA). We discuss the efficiency between the traditional optimum criteria methods(More)
In this paper, we deal with nonlinear integer programming problem with interval coefficients, and solve it directly keeping the nonlinearly of the objective function based on Hybrid Algorithm (HA) which is hybridized with the Genetic Algorithm (GA), Simulated Annealing (SA) method and Fuzzy Logic Controller (FLC) technique. Also, we demonstrate the(More)
