bench 3 - Direct

% I could use sum(vectorized_expr) but this form is more obvious
f = @(x) cos(10*x(1))+(x(1)-0.01)^2 + cos(20*x(2)) + (x(2)-0.02)^2 + ...
    cos(30*x(3)) + (x(3)-0.03)^2 + cos(40*x(4)) + (x(4)-0.04)^2 + ...
    cos(50*x(5)) + (x(5)-0.05)^2 + cos(60*x(6)) + (x(6)-0.06)^2 + ...
    cos(70*x(7)) + (x(7)-0.07)^2
Problem.f = f;
bounds = [zeros(1,7);ones(1,7)]';
opts.tol = 1e-2;
opts.maxevals = 100000;
opts.maxits = 10000;
tic
[ret_minval,final_xatmin,history] = Direct(Problem,bounds,opts);
