Method Details

simplify

public boolean simplify(Expression expression,
 Set<Structure1D.IntIndex> remaining,
 BigDecimal lower,
 BigDecimal upper,
 NumberContext precision)

The program logic here does not assume variables to be binary or even integer

Specified by:

simplify in class ExpressionsBasedModel.Presolver

Returns:

True if any model entity was modified so that a re-run of the presolvers is necessary - typically when/if a variable was fixed.
