Hello everyone.

I am running 'fmincon' for global optimization but some errors are occured.

The below is the code that I put

`%%`

P = [];P = P.';x0 = ones(243,1); TP = []; lb = zeros(243,1); ub = ones(243,1); aeq =[]; beq=[]; nonlcon_fmincon = [@nonlinearcon]; % Non-linear constraint we used for MOLP is stored in @nonlinearcon function

opts_mincon =optimoptions(@fmincon,'MaxFunctionEvaluations', 100000000000,'ConstraintTolerance',1e-5);%%

rng defaultgs = GlobalSearch;C = [123935;85425;96389;79871;138338;.....;27614];C = C.';fun_C = @(x)-C*x;problem = createOptimProblem('fmincon','nonlcon',nonlcon_fmincon,'x0',x0,'objective',fun_C,'LB',lb,'UB',ub);x = run(gs,problem);

The error messages are follows;

`Error : createOptimProblem (line 107)No field LB exists for PROBLEM structure.Type "help createOptimProblem" for a list of valid fields for each solver.Error: Untitled (line 18)problem = createOptimProblem('fmincon','nonlcon',nonlcon_fmincon,'x0',x0,'objective',fun_C,'LB',lb,'UB',ub)`

I don't know which one has problem.

Thanks
