WebDec 21, 2024 · As we discussed in the introduction, the convergence analysis of IPOPT and many other nonlinear optimization solvers [14, 41] assumes that the set of dual multipliers at the convergence point is bounded to guarantee that the dual multipliers do not diverge. One natural question is whether these assumptions are valid on a test set like NETLIB.

Another option at your disposal is the convergence tolerance, found in the Options tab of the IPOPT profile. The default is 1e-8, which often is too low. Increasing this value to 0.001 or higher promotes much faster convergence.
