CoinWorkDouble complementarityGap() const
ComplementarityGap.
int solve()
Primal Dual Predictor Corrector algorithm.
This solves LPs using interior point methods.
bool checkGoodMove2(CoinWorkDouble move, CoinWorkDouble &bestNextGap, bool allowIncreasingGap)
: checks for one step size
int updateSolution(CoinWorkDouble nextGap)
updateSolution. Updates solution at end of iteration
void setupForSolve(const int phase)
setupForSolve.
void solveSystem(CoinWorkDouble *region1, CoinWorkDouble *region2, const CoinWorkDouble *region1In, const CoinWorkDouble *region2In, const CoinWorkDouble *saveRegion1, const CoinWorkDouble *saveRegion2, bool gentleRefine)
Does solve.
void debugMove(int phase, CoinWorkDouble primalStep, CoinWorkDouble dualStep)
See exactly what would happen given current deltas.
This solves LPs using the predictor-corrector method due to Mehrotra.
