Hello
I will give an example of find minimum value of objective function
First, we can create the objective function, named by U(x), for example
function res = U(x)
res = sqrt(x(1)^2 + x(2)^2 + x(3)^2 + ...
x(3)^2 + x(4)^2 + x(5)^2);
Then, we can use the globalsearch as follows
problem = createOptimProblem('fmincon','objective', ...
@(x) U(x), 'x0', [1 1 1 1 1], 'lb', [-3 -3 -3 -3 -3], ...
'ub', [3 3 3 3 3]);
gs = GlobalSearch;
[x, f] = run(gs, problem)
where x0 = [1, 1, ..., 1] is the initial guess, lb is the lower bound of the varibale, ub is the upper bound of the variable and x is the optimal solution, f is the minimum value of the objective function corresponding to x.
Best regards,
Trung
