Detailed Description

fixing roundable variables to best bound

Tobias Achterberg

This propagator fixes variables, that have no restrictions in direction of their objective coefficient, to the best possible value. If the objective coefficient of a variable is \(0\) and it may be rounded both up and down, then this variable will be fixed to the closest feasible value to \(0\).
