Abstract: In this paper, several kinds of deviation integrals for global optimization are constructed. Their global minimization is solved and studied. To implement 100 variables of the algorithm with the Monte-Carlo technique, different deviation integrals for global optimization are used. Numerical tests show that the different deviation integrals have advantages for different objective functions.
