Population maintenance strategy combining diversity with convergence for 2-objective problem
Xiao Gui-xia · Computer Engineering and Applications Journal · 2008
Population maintenance is an important issue in multi-objective evolutionary algorithms.For the traditional methods only concentrate on the distribution of solutions,a population maintenance strategy with both diversity and convergence considered is proposed.This measure assigns fitness with relative convergent relationship during neighboring individuals,which compensated the coarseness of the simple Pareto dominance relation effectively,and controlled crowding degree with an adjustable neighborhood method.Comparing with NSGA-II and SPEA2,this algorithm can maintain diversity of the population effectively,and have a good convergence and running time.
