WebJul 6, 2024 · By analyzing Ipopt's output. Total CPU secs in IPOPT (w/o function evaluations) = 30.153 Total CPU secs in NLP function evaluations = 203.782 we can see that the evaluation of your functions is the bottleneck. So let's try to profile your code as Tom suggested in the comments: WebIPOPT. IPOPT (Interior Point OPTimizer) is a software library for large scale nonlinear optimization of continuous systems. ... Automatic differentiation, generates this matrix (dense or sparse) automatically, while OpenOpt problems coded in pure Python language just pass matrix with all ones; ...

The apopt.py program acts like an executable with the model.nl as an argument to the solver and it produces a sol solution file that is then processed to retrieve the solution. Unlike other solvers in AIMS or Pyomo, APOPT computes remotely on a public server. dalling construction stratford
