Parameter set/get methods
The set methods return true if the parameter was set to the given value, false otherwise.

There can be various reasons for failure: the given parameter is not applicable for the solver (e.g., refactorization frequency for the volume algorithm), the parameter is not yet implemented for the solver or simply the value of the parameter is out of the range the solver accepts. If a parameter setting call returns false check the details of your solver.

The get methods return true if the given parameter is applicable for the solver and is implemented. In this case the value of the parameter is returned in the second argument. Otherwise they return false.

once it has been decided where solver sits this may be redone

Detailed Description

This is the base class for Linear and quadratic Models This knows nothing about the algorithm, but it seems to have a reasonable amount of information.

I would welcome suggestions for what should be in this and how it relates to OsiSolverInterface. Some methods look very similar.
