Constructor & Destructor Documentation

◆ CouenneSolver()

CouenneSolver::CouenneSolver ( )

the CouenneSolver class constructor

◆ ~CouenneSolver()

CouenneSolver::~CouenneSolver ( )

the IpoptSolver class destructor

Member Function Documentation

◆ solve()

virtual void CouenneSolver::solve ( )
throw (ErrorClass
)
virtual

solve results in an instance being read into the Couenne data structrues and optimized

Implements DefaultSolver.

◆ buildSolverInstance()

virtual void CouenneSolver::buildSolverInstance ( )
throw (ErrorClass
)
virtual

buildSolverInstance is a virtual function – the actual solvers will implement their own buildSolverInstance method – the solver instance is the instance the individual solver sees in its API

Implements DefaultSolver.

◆ setSolverOptions()

void CouenneSolver::setSolverOptions ( )
throw (ErrorClass
)
virtual

The implementation of the virtual functions.

Returns
void.

Implements DefaultSolver.

◆ dataEchoCheck()

void CouenneSolver::dataEchoCheck ( )

use this for debugging, print out the instance that the solver thinks it has and compare this with the OSiL file

◆ writeResult()

void CouenneSolver::writeResult ( )

use this to write the solution information to an OSResult object
