function [v, x] = evaluate( prob, x )%EVALUATE function evaluate an individual structure of a vector point with%the given multiobjective problem.%   Detailed explanation goes here%   prob: is the multiobjective problem.%   x: is a vector point, or a individual structure.%   v: is the result objectives evaluated by the mop.%   x: if x is a individual structure, then x's objective field is modified%   with the evaluated value and pass back.%   TODO, need to refine it to operate on a vector of points.    if isstruct(x)        v = prob.func(x.parameter);        x.objective=v;    else        v = prob.func(x);    end
