I want to use the GA toolbox for optimization but with the parallel option ('UseParallel', true).
options = optimoptions(@ga,'Display', 'iter', ...
'OutputFcn',@GA_OUTPUT ,...
'PlotFcn', {@gaplotbestf, @PLOT_FUNCTION},...
'MaxGenerations', 60, ...
'PopulationSize', POPULATION_SIZE, ...
'FunctionTolerance',1e-6, ...
'CrossoverFraction', 0.95, ...
'EliteCount', 0.1*30,...
'UseParallel', true) ;
[x,fval,exitflag,output,population,scores] = ...
ga(@OBJECTIVE_FUNCTION,nvars,A,b,Aeq,beq,lb,ub,@POWER_CONSTRAINT,IntCon,options) ;
My question is how can I attach my working directory (/home/user/workidir) with the files to be used by the algorithm in each Worker.
Thanks.

Hi, thanks for your reply,
  1. No, Matlab starts the parallel calculation automatically.
  2. Yes, it is the PC that I use and that is the directory where I am running the code.
Thanks.
