Hi guys,

I am trying to run Genetic algorithm. I could run it with single object but I want to give multiple objects as input. Does anyone have any idea how could i do that.

classdef clGAalgorithm
    properties
% clSystem = 'path \ path'
% GOSET = 'path \ path'
% PATH = 'path \ path'
% PMD = 'path \ path'
            
            rp_lvl = 0;
            ev_pp = true;
            ev_npg = 12;
            gd
    end
    methods (Static)
        function [object, fP, GAS, bi, bf] = GA1 (objDS, objT)             % set up GA
            ngen = 2000;
            npop = 2000;
            object = gapdefault (2.0, npop, ngen);
% GAP.rp_lvl = 0;
% GAP.ev_pp = true;
% GAP.ev_npg = 12;

                    % conduct optimization
                    [fP, GAS, bi, bf] = gaoptimize (@ cloptim1.CTT_fit_Litz1, object, objDS);
                    % save the results
                    if objDS.MatCore == 1
                        save resultsSteelLitz
                    elseif objDS.MatCore == 2
                        save resultsFerriteLitz
                    elseif objDS.MatCore == 3
                        save resultsNanoLitz
                    else
                        disp ( 'No such material catalog for core' );
                        
                    end
        end
        

The object objDS which is given as input is working but i also want to give objects like objCore, objW, objT as inputs in addition to that. Since gaoptimize supports single input i think it supports in that way. but i also want to include other objects. Can give me some idea.

Thank you
