MATLAB: How to use a gatool in the Matlab 2014a

genetic algorithmMATLABoptimization

I'm using Matlab 2014a version.

I want to use genetic algorithm to do optimisation but I couldn't find a GA solver in 'optimtool' GUI and when I try to enter the tool by typing 'gatool' in command window, it returns 'Undefined function or variable 'gatool'.'.

So how can I access GA in my Matlab.

It sounds like you have the Optimization Toolkit installed but not the Global Optimization Toolkit; ga is part of Global Optimization

dbstop if error

Which will stop deep inside of ga(). Now put a break point in first line of your objective function. Run the feval line that causes the error and step through your fitness function to find the error and analyze the inputs.

Perhaps the documentation on defining fitness functions can help. Or perhaps the documentation on bit string population can help.

Good luck,
