WebSep 18, 2024 · Introduction. The -new_grid option interpolates from one grid into another. The -new_grid_interpolation option selects the interpolation method. The -new_grid_ipopt option modifies the parameters used by the interpolation method. The -new_grid_ipopt option MUST FOLLOW the -new_grid_interpolation option because the latter will … 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. showtime competition schedule

"WebApr 28, 2016 · The only constraints that Ipopt is guaranteed to satisfy at all intermediate iterations are simple upper and lower bounds on variables. Any other linear or nonlinear equality or inequality constraint will not necessarily be satisfied until the solver has finished converging at the final iteration (if it can get to a point that satisfies termination conditions).
