nip

Use a nonlinear interior point method for solving an optimization sub-problem

Specification

  • Alias: None

  • Arguments: None

Description

Many uncertainty quantification methods solve a constrained optimization problem under the hood. The nip keyword directs Dakota to use a nonlinear interior point algorithm to solve the subproblem. A nonlinear interior point method traverses the interior of the feasible region to arrive at the optimal solution.
