hi
i have two functions(f1,f2).i want to optimization functions with multi-objective genetic algorithm.i want,weight for f1 and f2 where f1=0.3 and f2=0.7
function f = simple_multiobjective222(x)
f(1) = 0.0002169*(x.^0.5)*(-1)*(10000);
f(2) = ((12.85)*(x.^(-1)))+((17.72)*(x.^0.5));
FitnessFunction = @simple_multiobjective222;
numberOfVariables = 1;
[x,fval] = gamultiobj(FitnessFunction,numberOfVariables);
size(x)
size(fval)
A = []; b = [];
Aeq = []; beq = [];
lb = 3;
ub = 17.55;
x = gamultiobj(FitnessFunction,numberOfVariables,A,b,Aeq,beq,lb,ub);
options = optimoptions(@gamultiobj,'PlotFcn',{@gaplotpareto,@gaplotscorediversity});
gamultiobj(FitnessFunction,numberOfVariables,[],[],[],[],lb,ub,options);
please help me.
thanks.

Perhaps this example will help, especially the section Find Good Parameters from Plot.
But if I misunderstood what you were asking, please ask again, specifying more clearly what you want.
