+%% Random Search Algorithm (Pure Random Search Algorithm)

+% This code finds the minimum of f(x) = x(1)^2 + x(2)^2
+% in which -5 < x(i) < 5
+% This function is a convex and the minimum is at (0,0)
+% The RSA is the simplest algorithm to solve optimization problem
+% it is not efficient and it sometimes cannot solve the problem
