英文摘要：

In this paper, the optimization problems with nonlinear inequality and equality constraints are discussed. With the help of strongly sub-feasible direction method and the idea of semipenalty function, a new generalized projection of strongly sub-feasible direction method for the discussed problems is proposed. An outstanding property of the proposed algorithm is that the iteration points can enter into the feasible region of the semi-penalty problem after a finite number of iterations. Under some suitable conditions, the globally and strongly convergent properties are obtained. The numerical experiments show that the proposed algorithm is promising.
