WORHP has been designed to solve small to very large-scale nonlinear optimisation problems, with an emphasis on solving large-scale, sparse problems arising from full discretisation of optimal control problems.

Flowchart of WORHP

The capabilities of WORHP are continually being tested on a growing set of applications and standard NLP test problems, CUTEr being the most important one of them. As new sets are being integrated into the regular WORHP testing machinery, they will be added here.
