IPOPT (Interior Point OPTimizer) is a software package for large-scale ​nonlinear optimization, designed to find local solutions of mathematical optimization problems. IPOPTLink is a Wolfram System application that uses Wolfram LibraryLink to link to IPOPT functions. It is used automatically by the Wolfram Language in optimization functions such as FindMinimum. However, it can also be used directly providing a more flexible way to use the functionality of IPOPT.

IPOPTMinimize — numerically solves an optimization problem

ParametricIPOPTMinimize — sets up an optimization problem with parameters

IPOPTData — represents a solution instance generated by IPOPTMinimize

IPOPTMinValue — returns the minimal objective function value

IPOPTArgMin — returns the position of the local minimum

IPOPTReturnCode — gives the IPOPT solver return code

IPOPTDataExpressions — lists all active IPOPTData expressions
