One is a large scale nonlinear programming model with equalities, the other is a more complicated NP hard and nonlinear compound 0-1 programming model. It is difficult for the existed algorithms to fulfill the demands of efficiency and size for the above problems. Two corresponding genetic algorithms are presented, in which several suitable genetic operations are constructed to make the optimization search process in the range of feasible solutions.
