why my matlab codes do not give correct answer in genetic algorithm for solving facility problem

I study a bacholer thesis about a genetic algorithm for solving facility location problems . I have 4 facility and 20 customer. Products are sent from facility to customer. I have data set about this problem.Objective function is to minimized cost. I calculated optimal value in GAMS software with data set. I wrote a genetic algoritm code in matlab. Matlab result is not similar or close GAMS result. GAMS result is 40437 abou cost.in my opnion I am missing a thing. I attached my documentations and matematical model in here. Can you arrange this codes. Can you help me?

hello,

in your cities data, matrix size is 5*4, as far i know, 5 is the number of facility but i dont know what are 4 columns.

in supply data too, there are 4 columns for each facility.

can you explain?

thanks

Dear burak karadem,

I read tried to run your code I found that you did not set your popsize, probcross, probmut, and iteration. So i set them like this as trail to get a result. but in every time i got the error down

popsize=10;

probcross=0.4;

probmut=0.2;

iteration=2;

Attempted to access sumfix(10,:); index out of bounds because size(sumfix)=[9,5].

Error in objectivecalc (line 44) cost1(i)=sum(sumfix(i,:));

Error in genetic (line 77) cost = objectivecalc( supply,cities, popsize, population,transcost,fixcost,dist,cusdemand);

you post your problem in 2017 and just read it. I wonder if you fixed your code. If so could you please tell me what is wrong and why i get this error.

Many thanks,
