Customising creation function in GA optimisation tool

조회 수: 5(최근 30일)
Bus route network design problem aims to find an optimal set of routes that satisfies a predefined objective and a set of constraints. This is to be optimized using genetic algorithm. If an initial population of N individuals is to be formed from a set of routes stored as a cell array, is it possible to customize the genetic algorithm optimization tool in Matlab for this?

Yes, See the Initial Population options. Once you have read through these and determine what your Initial population is, you can use it by creating your optimoptions structure.
IP = ... % Population MAtrix goes here
options = optimoptions('ga','InitialPopulationMatrix',IP);
x = ga(fitnessfcn,nvars,A,b,Aeq,beq,LB,UB,nonlcon,options)

This example might give you ideas on a possible approach. It is not a direct solution to your problem, but I think it shows that the approach is workable.

You don't have to give a complete initial population. In other words, m can be smaller than the population size. See Initial population.
