Constrained Nonlinear Optimization Algorithms Constrained Optimization Definition. Constrained minimization is the problem of finding a vector x that is a local minimum to a scalar function f(x) subject to constraints on the allowable x: min x f (x) such that one or more of the following holds: c(x) ≤ 0, ceq(x) = 0, A·x ≤ b, Aeq·x = beq, l ≤ x ≤ u. There are even more constraints. Solve nonlinear minimization and semi-infinite programming problems in serial or parallel using the solver-based approach.
