IPOPTMinValue

IPOPTMinValue[data] gives the minimal value of the objective function from an IPOPTData expression data.

Details and Options

First, load the package:

Wolfram Language code: Needs["IPOPTLink`"]

Solve a minimization problem using IPOPTMinimize:

Wolfram Language code: sol = IPOPTMinimize[Cos[x + y] * Sin[x - y], {x, y}, {0, 1}, {{-1, 1}, {-1, 1}}, {Sin[x], x * y}, {{-1, 0}, {-.25, .0}}]

Extract the minimal objective function value from the IPOPTData expression:

Wolfram Language code: IPOPTMinValue[sol]

The position where the minimal value was found is the minimization point:

Wolfram Language code: {pos = IPOPTArgMin[sol], Cos[x + y] * Sin[x - y] /. Thread[{x, y} -> pos]}
