چکیده

This paper is the next installment in a series (Sobieszczanski-Sobieski et al. 1998, Kincaid et al. 2000, 2001, 2002 and Plassman and Sobieszczanski-Sobieski 2000) that has introduced a variant of the Genetic Algorithm in which the reproduction mechanism was modified to base it on the Gaussian probability distribution, the bell curve. The bell-curve based (BCB) heuristic procedure, first presented in Sobieszczanski-Sobieski, Laba, and Kincaid (1998), is similar in spirit to Evolutionary Search strategies (ESs) and Evolutionary Programming methods (EPs) but has fewer parameters to adjust. In Sobieszczanski-Sobieski et al. (1998) BCB was tested on a structural design optimization problem. The quality of solutions generated were verified by comparing BCB solutions to ones generated by a standard nonlinear programming technique. No attempt was made to analyze the sensitiv-

FORCED WATER MAIN DESIGN MIXED ANT COLONY OPTIMIZATION

Most real world engineering design problems, such as cross-country water mains, include combinations of continuous, discrete, and binary value decision variables. Very often, the binary decision variables associate with the presence and/or absence of some nominated alternatives or project’s components. This study extends an existing continuous Ant Colony Optimization (ACO) algorithm to simultan...

DISCRETE AND CONTINUOUS SIZING OPTIMIZATION OF LARGE-SCALE TRUSS STRUCTURES USING DE-MEDT ALGORITHM

Design optimization of structures with discrete and continuous search spaces is a complex optimization problem with lots of local optima. Metaheuristic optimization algorithms, due to not requiring gradient information of the objective function, are efficient tools for solving these problems at a reasonable computational time. In this paper, the Doppler Effect-Mean Euclidian Distance Threshold ...

Research of Blind Signals Separation with Genetic Algorithm and Particle Swarm Optimization Based on Mutual Information

Blind source separation technique separates mixed signals blindly without any information on the mixing system. In this paper, we have used two evolutionary algorithms, namely, genetic algorithm and particle swarm optimization for blind source separation. In these techniques a novel fitness function that is based on the mutual information and high order statistics is proposed. In order to evalu...

DISCRETE SIZE AND DISCRETE-CONTINUOUS CONFIGURATION OPTIMIZATION METHODS FOR TRUSS STRUCTURES USING THE HARMONY SEARCH ALGORITHM

Many methods have been developed for structural size and configuration optimization in which cross-sectional areas are usually assumed to be continuous. In most practical structural engineering design problems, however, the design variables are discrete. This paper proposes two efficient structural optimization methods based on the harmony search (HS) heuristic algorithm that treat both discret...
