Global Optimization toolbox: "Undefined function or variable 'createOptimProblem'"
显示 更早的评论
I am trying to use Global Search to solve my optimization problem. Can anyone please help me with this error? Thanks.
"Undefined function or variable 'createOptimProblem'.
Error in globalsearch (line 9)
problem = createOptimProblem('fmincon','x0',x0,..."
This is my code:
opts = optimoptions(@fmincon,'Algorithm','interior-point');
obj=@obj_fun; % objective function of the problem
cons=@nonlcon; % nonlinear constraints of the problem
lb=[0 0 0 0 0 0];
ub=[300 300 300 300 150 1];
x0=[60 30 0.05 16 50 0.5];
problem = createOptimProblem('fmincon','x0',x0,...
'objective',obj,'lb',lb,'ub',ub,'nonlcon',cons,...
'options',opts);
gs= GlobalSearch;
[x ,fval,eflag,outptg,solutions] = run(gs,problem,10);

Nam - do you have the Global Optimization Toolbox? In the Command Window, type
ver
to list your version of MATLAB and all installed toolboxes. Note that the createOptimProblem is mentioned in the R2014a documentation (see http://www.mathworks.com/help/releases/R2015a/gads/release-notes.html) so perhaps it was introduced in this version of the toolbox.
