For the modeling of some significant components in sexual selection, including the concepts of male trait and
female mating preference, evolutionary framework is constructed. The theoretical principle of this framework is the famous
mechanism called Fisher’s runaway process. Numerical optimization is carried out to evaluate the newly proposed framework
on a large number of benchmark functions used in CEC2005 Special Session. Experimental results show that the proposed
framework outperforms the classic real-coded genetic algorithm on most functions.
