18  * @brief Simple and fast LP rounding heuristic
19  * @author Tobias Achterberg
20  *
21  * Simple rounding is a very cheap heuristic that iterates over the set of fractional variables of an LP-feasible
22  * point. It only performs roundings for variable that have zero up- or downlocks. Hence, they are guaranteed to keep
23  * all constraints satisfied. If all fractional variables can be rounded that way, the resulting solution will bve
24  * integral and LP-feasible.
