Member Function Documentation
| double ABA_Variable::coeff | ( | ABA_CONSTRAINT * | c | ) | [virtual] |
Computes the coefficient of the variable in the constraint c. Per default the coefficient of a variable is computed indirectly via the coefficient of a constraint. Problem specific redefinitions might be required.
- Returns:
- The coefficient of the variable in the constraint c.
- Parameters:
-
c The constraint of which the coefficient should be computed.

| int ABA_Variable::genColumn | ( | Active_Inequalities * | ai, | |
| Column & | col | |||
| ) | [virtual] |
Computes the column col of the variable associated with the active constraints *ai.
- Note:
- The upper and lower bound of the column are initialized with the global upper and lower bound of the variable. Therefore, an adaption with the local bounds might be required.
- Returns:
- The number of nonzero entries in col.
- Parameters:
-
ai The constraints for which the column of the variable should be computed. col Stores the column when the function terminates.
