Non - convexity is in general the main feature of the difficulties for solving these models for wastewater treatment network optimization
它们是具有非凸性的复杂非线性数学规划问题，用现有的方法进行求解不能保证得到全局最优解。
2 . reliability of rock slope was done using responding surface method ( rsm ) and monte - carlo method ( mcm ) respectively . reliability index 0 calculated by rsm and mcm are different , which indicates the non - convexity of limit state curved surface in representation of stability of slope
采用响应面法( rsm )和monte - carlo法( mcm )对边坡进行了可靠度分析，两者计算所得的可靠指标存在着一定的差异，这表明：代表边坡稳定的极限状态曲面存在着非凸性。
