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.
