Multiobjective Design Optimization of Grillage Systems according to LRFD-AISC

Algorithm 3

A pseudocode for PESA II procedure.

initialize archive = AdaptiveGridArchive (archive_size, bisections)

initialize solutionSet (population_size)

initialize solution (population_size)

solution = PESAIIselection (solution)

evaluate solution, evolution ++

solutionSet.add(solution)

archive.add(solutionSet)

solutionSet.clear

while evolution < max_evolution {

    offspring=mutation(crossover(selection(archive)))

    evaluate offspring, evolution ++

    solutionSet.add(offspring)

    archive.add(solutionSet)

    solutionSet.clear}
