Member Function Documentation

void CoinSolver::solve	(		)
throw	(	ErrorClass
	)

virtual

The implementation of the corresponding virtual function.

Returns: void.

Implements DefaultSolver.

Definition at line 1100 of file OSCoinSolver.cpp.

void CoinSolver::buildSolverInstance	(		)
throw	(	ErrorClass
	)

virtual

The implementation of the corresponding virtual function.

Returns: void.

Implements DefaultSolver.

void CoinSolver::setSolverOptions	(		)
throw	(	ErrorClass
	)

virtual

The implementation of the corresponding virtual function.

Returns: void.

In this first pass through the options just see if the hintStrength was set

If the hintStrength was set, use it when processing the other options

Implements DefaultSolver.
