It has an original OsiClpSolverInterface and CbcModel which it can use repeatedly, e.g., to get a heuristic solution and then start again.
So I [jjf] will need a primitive scripting language which can then call solve and manipulate solution value and solution arrays.
Also provides for user callback functions. Currently two ideas in gestation, CbcUser and CbcStopNow. The latter seems limited to deciding whether or not to stop. The former seems completely general, with a notion of importing and exporting, and a `solve', which should be interpreted as `do whatever this user function does'.
Parameter initialisation is at last centralised in fillParameters().

CbcSolver::CbcSolver | ( | ) |
Default Constructor.
CbcSolver::CbcSolver | ( | const OsiClpSolverInterface & | ) |
Constructor from solver.
CbcSolver::CbcSolver | ( | const CbcModel & | ) |
Constructor from model.

CbcSolver::~CbcSolver | ( | ) |
Destructor.
int CbcSolver::solve | ( | int | argc, | |
const char * | argv[], | |||
int | returnMode | |||
) |
This takes a list of commands, does "stuff" and returns returnMode - 0 model and solver untouched - babModel updated 1 model updated - just with solution basis etc 2 model updated i.e.
as babModel (babModel NULL) (only use without preprocessing)
int CbcSolver::solve | ( | const char * | input, | |
int | returnMode | |||
) |
This takes a list of commands, does "stuff" and returns returnMode - 0 model and solver untouched - babModel updated 1 model updated - just with solution basis etc 2 model updated i.e.
as babModel (babModel NULL) (only use without preprocessing)
void CbcSolver::fillParameters | ( | ) |
Fill with standard parameters.
void CbcSolver::fillValuesInSolver | ( | ) |

Misleading. The current code actually reads default values from the underlying solvers and installs them as default values for a subset of parameters in parameters_.
