%% crossoverOperator2
% Function: Single point cross over operator without size restriction
% Input:
%     individual1:    first parent
%     individual2:    second parent
% 
% Output:
%     crossedIndividual1: first offspring individual
%     crossedIndividual2: second offspring individual
%     flag:
%         true - the crossover is sucesfully applied
%         false - the crossover is not sucesfully applied
function [crossedIndividual1,crossedIndividual2,flag] = crossoverOperator2(individual1,individual2)
    sizeChromosome = numel(individual1);
    crossPoint = randi(sizeChromosome-3,1,1) + 1;
    crossedIndividual1(1,:) = [individual1(1,1:crossPoint) individual2(1,crossPoint+1:end)];
    crossedIndividual2(1,:) = [individual2(1,1:crossPoint) individual1(1,crossPoint+1:end)];
