Genetic Algorithm with Array as variable
显示 更早的评论
So say I have some array at the beginning of a very long code. And at the end the program outputs a single value. How do I get the genetic algorithm tool to change the values of each element in the array to minimize the output value? This may be something simple but I cannot find a method or example on how to do this. Thanks for your time!

All you have to do is change your array to a row vector, something like this:
input = x(:)';
Here x represents your array of variables (known as decision variables) that the optimizer changes to minimize the output value (known as the objective function or, for ga, the fitness function). Then input is the set of variables that ga evaluates for finding a minimum.
Good luck,

I have same problem , and I do this step for my variables :
input = x(:)';
but Genetic algorthim code not work with it , how can I fix it ?

I have no idea what your inputs and function call are, so how can I comment? I suggest that you ask a new question (I mean start a new Answers topic) and give some detail. Include your function call ([x,fval] = ga(whatever)) and your options.
