I use the optimtool MATLAB tool. Specifically I run a genetic algorithm (ga) for simulation purposes. There are some variables which change their values inside the loop of ga. Two of them are "funccount" and "generations". These corresponds to the Total number of function evaluations, and Total number of generations, excluding HybridFcn iterations, respectively. May I use these or an additional counter, manual increasing, variable (for example, i = i + 1) interfering inside the genetic algorithm loop? I would like to see this value changing in my Command Window.
Is there any idea? Thank you in advance!
Write the following before calling ga function:
options = gaoptimset;
options = gaoptimset(options,'PopulationSize',100);
options = gaoptimset(options,'Generations',1000);
options = gaoptimset(options,'TolFun',0);
options = gaoptimset(options,'TolCon',0);
options = gaoptimset(options,'Display','iter');
options = gaoptimset(options,'PlotFcns',{@gaplotbestf @gaplotbestindiv});
options = gaoptimset(options,'Vectorized','on');
In addition I mention that I would like to use this value (as a counter) instead of just represent it in the Command Window. Because, when I am going to write for example disp(generations) MATLAB doesn't understand the value 'generations' (corresponding to the iterations). Do I have to write something more complicated to use this value in my calculations? Thank you in advance!
Dear Panagiotis Dimakopoulos,
You can define your desired variable as a global one in the fitness function and thereafter it will be accessible anywhere in your code.
