| Abstract | Genetic algorithms are search procedures based upon the mechanics of natural genetics, combining a Darwinian survival-of-the-fittest philosophy with a random yet structured information exchange among a population of artificial chromosomes. As a result, the superior offspring will be created whereas the inferior ones will be destroyed. Genetic algorithms can be utilized only for an unconstrained problem; therefore a constrained problem must be transformed to an unconstrained problem. A genetic algorithm is integrated with augmented Lagrangian method in a nested loop. A 32m-TOT's telecommunication tower is selected and tested with two categories, i.e. allowable compressive stress equals allowable tensile stress and allowable compressive stress equals 70% of allowable tensile stress. Each category is also divided into 4 cases of different crossover method, I-point, 2-point, 20%-uniform, and 50%-uniform crossover. Numerical results are presented to show the efficiency of the method |
