WebJul 18, 2024 · Ipopt performs very poorly as it struggles to find a feasible solution. It finds the right optimum in maybe 5 % of the cases. Now both ipopt and SQP are local solvers, so the solutions should not be that much different. I tried Matlab's own ipopt, as well as ipopt supplied by opti-toolbox. Both perform miserably compared to Matlab's SQP.
