WebAlong the same lines, IPOPT will sometimes slow down substantially or not converge at all. 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. 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.

Webvirtual bool Ipopt::ConvergenceCheck::CurrentIsAcceptable. (. ) pure virtual. Method for testing if the current iterate is considered to satisfy the "acceptable level" of accuracy. The idea is that if the desired convergence tolerance cannot be achieved, the algorithm might stop after a number of acceptable points have been encountered ...
