I am doing optimization problem. The objective function requires to call external program. But time for calling the program (0.1s) is much longer than the analysis of external program itself (0.01s). The optimization needs thousands of iteration to find optimum solution, so this takes hours. Is there a way to shorten the time for calling external program as it consumes most of required time?
Example of my script:
% Optimization
x = ga(@fun,100);
% Objective function
function y = fun(x)
% writing input for external program
fprintf(fopen('input.tcl','wt'),'%s\n',x);
% running external program
!opensees.exe analysis.tcl
% read analysis result
out = fscanf(fopen('output.tcl','r'),'%f',[100 Inf]);
% objective function
y = fun2(out);
end

@per isakson: Yes I've tried to google it, but I still can't understand it, I am not from IT background.
@Mario Malic: Oh that's good idea, I will try find a way to do that. Thanks.
