Detailed Description

Convert an explicit bound constraint to a column bound.

This transform looks for explicit bound constraints for a variable and transfers the bound to the appropriate column bound array. The constraint is removed from the constraint system.

Member Function Documentation

const char* slack_doubleton_action::name ( ) const

A name for debug printing.

It is expected that the name is not stored in the transform itself.

Implements CoinPresolveAction.

Definition at line 50 of file CoinPresolveSingleton.hpp.

static const CoinPresolveAction* slack_doubleton_action::presolve ( CoinPresolveMatrix prob,
const CoinPresolveAction next,
bool &  notFinished 

Convert explicit bound constraints to column bounds.

Not now There is a hard limit (#MAX_SLACK_DOUBLETONS) on the number of constraints processed in a given call. notFinished is set to true if candidates remain.

void slack_doubleton_action::postsolve ( CoinPostsolveMatrix prob) const

Apply the postsolve transformation for this particular presolve action.

Implements CoinPresolveAction.
