Convert explicit bound constraints to column bounds. |
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.

A name for debug printing.
It is expected that the name is not stored in the transform itself.

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.
