WebMay 13, 2015 · I edited this question based on information I got from comments. Assume we have an optimization problem (primal problem). we solve it's dual using some kind of primal-dual interior point solver. So, we have multipliers of constraints of the dual or any other relevant information. The primal-dual method's idea is easy to demonstrate for constrained nonlinear optimization. For simplicity, consider the following nonlinear optimization problem with inequality constraints: This inequality-constrained optimization problem is solved by converting it into an unconstrained objective function whose minimum we hope to find efficiently. Specifically, the logarithmic barrier function associated with (1) is
