Why ga gives different results on graphic and fval value

Hi. I m using ga for my problem. But , it gives different results on graphic(PlotFcns',{@gaplotbestf,@gaplotstopping}) and for fval value. I entered all input values in A matrix , and I described ub,lb, function and others as below.

[x,fval,exitflag,output] = ga(@modellp,nvars,A,b,[],[],lb,ub,[ ],intcon ,options);

and my opitons is

options = gaoptimset('PopulationSize',50,'Generations',10000,'EliteCount',3,'TolFun',1e-10,'PlotFcns',{@gaplotbestf,@gaplotstopping} );

I solved same problem with intlinprog , and I took good results. But ga always gives error. What is the problem, could you help me?

Hi Halime!

I know it has been quite a long time since you worked on this, but I seem to have the exact same problem as yours, and could not find any answer anywhere.

Did you manage to understand the difference between fval and the best score on the graphic?

Thanks in advance,

All the best,
