Examples: IPNLP Solver

In this section, several examples are presented to illustrate the capabilities and features of the IPNLP solver. Problems that contain a small number of variables and constraints are solved by using the quasi-Newton technique of IPNLP (TECH=IPQN), whereas problems with many thousands of constraints and variables are solved with the iterative trust-region interior point algorithm (TECH=IPKRYLOV).
