Based on the cascaded gaps, we …

"WebThe optimality conditions are derived by assuming that we are at an optimum point, and then studying the behavior of the functions and their derivatives at that point. The conditions that must be satisfied at the optimum point are called necessary. Stated differently, if a point does not satisfy the necessary conditions, it cannot be optimum.
