reading file in objective function optimization
显示 更早的评论
Im using genetic algorithm to optimize a function, but in my objective function there are xlsread, and lots of load .mat file. I try using ga, but it is very slow. After 2 hours there is still nothing yet (i use 'PlotFcn', @gaplotbestf). I searched around and did find this https://www.mathworks.com/matlabcentral/answers/602392-genetic-algorithm-run-time-and-result-analysis#comment_1031587
one of their suggestion is to avoid read file in objective function, which i have a lot, like xlsread and load .mat files. And they suggest that using pameter function, which i dont understand. Can someone suggest how to avoid reading file in objective function, or explain what did they mean when they say should use parameter function?
Thank you.

Read the files into Matlab variables before you run your optimization. Make the variables fixed data in your objective function using anonymous or nested functions as described here:
