1Blurb:: 2Uses a nonlinear interior point method for underlying optimization 3 4Description:: 5Many uncertainty quantification methods solve a constrained optimization problem under the hood. The \c nip keyword directs Dakota to use a nonlinear interior point to solve that problem. A nonlinear interior point method traverses the interior of the feasible region to arrive at the solution to the optimization problem. 6 7Topics:: 8Examples:: 9Theory:: 10Faq:: 11See_Also:: 12
