Primal algorithm for quadratic Using a semi-trust region approach as for pooling problem This is in b...
int algorithm() const
Current (or last) algorithm.
int pivotColumn(CoinIndexedVector *longArray, CoinIndexedVector *rowArray, CoinIndexedVector *columnArray, CoinIndexedVector *spare, int &pivotMode, double &solutionError, double *array1)
longArray has direction pivotMode - 0 - use all dual infeasible variables 1 - largest dj while >= 10 ...
This solves non-linear LPs using the primal simplex method.
Quadratic Objective Class.
