OPT++ Documentation

Version 2.4

Introduction

OPT++ is a C++ library of nonlinear optimization algorithms. The motivation for this package is to build an environment for the rapid prototyping and development of new optimization algorithms. In particular, the focus is on robust and efficient algorithms for problems in which the function and constraint evaluations require the execution of an expensive computer simulation.

Currently, OPT++ includes the classic Newton methods, a nonlinear interior-point method, parallel direct search, a trust region - parallel direct search hybrid, a generating set search, and a wrapper to NPSOL. Between these methods, a wide range of problems can be solved, e.g. with or without constraints, with or without analytic gradients, simulation based, etc.
