CPLEX Integration in HeuristicLab

Reported by: abeham Owned by: abeham
Priority: medium Milestone: HeuristicLab 3.3.15
Component: General Version: 3.3.14

Description

It would not be difficult to achieve a generic integration of CPLEX into HeuristicLab.

The model file can simply be loaded by opening a .mod file.

What we need to do is wrap the HeuristicLab problem into a CustomOPLDataSource and provide the parameters that are specified as inputs in the .mod file. This class need not be serialized and thus we could provide a scripting view for writing such a data source.

In addition, this data source class should then also handle the creation of result data from running the model through the solver.

A difficulty is the reference to oplall.dll. We should not include it in the plugin, since we don't really know which version of the CPLEX Optimization Studio is running at the respective client. But this means that it should be in the PATH environment variable, otherwise the plugin infrastructure won't find it.
