19  Important Information

Setting patterns is especially important for large-scale problems as memory needs to be managed more properly (a dense problem is normally assumed otherwise).

19.1  Connector Panel

Observe that the connector panel in user created VI's need to match the setup as shown in the quick guide examples. If not, the reference cannot be established and an error will be displayed.

19.2  Using Patterns

For most problems it is critical to set the proper problem patterns (e.g. ConsPattern) for memory allocation purposes and to speed up numerical differentiation. If analytical derivatives are given only the memory benefit will be seen.

19.3  Solver Timings

Comparing different solvers with solution times under 5-10 seconds may yield incorrect results. When running a problem and a solver for the first time general overhead and loading of dll's consume the majority of the time. It is recommended to run several times to get a good average runtime.
