Ipopt max iteration

WebIpopt implements an interior-point algorithm for continuous, nonlinear, nonconvex, constrained optimization problems. It is meant to be a general purpose nonlinear programming (NLP) solver. However, it is mainly written for large-scale problems with up to million of variables and constraints. WebGAMS/IPOPT understands currently the following GAMS parameters: reslim (time limit), iterlim (iteration limit), domlim (domain violation limit). Further the option threads can be …

WebApr 20, 2024 · I am using Ipopt via the C wrapper in here. I would like to do so in order to reuse common calculations. In the MWE I show there are no common calculations, but the goal is to have a single function that can perform the three things depending on what is needed in each iteration (some iterations do not calculate the Hessian, for example). WebJul 31, 2024 · I've been using IPOPT in Julia to solve a nonlinear optimization problem. When I change the following equality constraint to the inequality constraint, the optimization iteration always exceeds the maximum number. And I have changed the maximum number from default 3000 to 100000 but it still doesn't work.
