equivalence problem meaning in English

等价问题

Motivated by the above results , the third part of this paper considers the equivalence problems that every stationary point or kuhn - tucker point is an efficient solution . we define i - quasi - invex vector function . , i - strictly quasi - invex vector function and kt - i - strictly quasi invex vector function , and derive the above equivalent condition for unconstrained or constrained multiobjective programming
于是，在本文的第三部分，我们定义了类不变拟凸、类严格不变拟凸、 kt -类严格不变拟凸的向量值函数，并且在无约束或约束多目标规划中，获得了每个驻点(或k - t点)是有效解的等价条件。
