Hi All,
I can attach the code I am working on if it helps but my question is more general than that. I am looking to minimize an output by optimizing one of the input variables, using a genetic algorithm. The catch is, I know the output variable is going to be a 20x50 array and one of those values is a minimum. I want to find the minimum of the output variable by optimizing the input variable but I keep getting the error message "Unable to perform assignment as left side is 1by1 and right side is 20x50". Any idea as to why I keep getting that, or would you need the code?
Edit: I have attached a zip file with all the files you need. They all need to be on the path. "expoSinWrapper" is the objective function needing to be minimized, and tof_1 and k2 are the variables that need to be optimised. "attempt_2" is the ga implementation, and "mapvariables" is just some mapping I am attempting. There is a lot of fluff from combinations I have tried to fix my own error, that I have commented out. In layman's terms I am trying to minimize M_Fuel, by optimising a combination of k2 and tof_1. I hope that is clear and helpful. The newest error is the assignation to k2,
it says index exceeds array bounds, but from the documentation I thought you were allowed to do that for multi variable optimisation?
EDIT 2: I fixed the problem, it was in the initialisation of the GA. Now the problem is that the fval being returned is the abnormally high one I set for errors in the objective function, meaning there isn't an optimisation occuring. Apologies for the messy question. Can anyone help?
