21 * ZI Round (C. Wallace, Journal of Heuristics 2009) reduces the integer infeasibility of an LP solution step-by-step by
22 * shifting fractional values towards integrality, but not necessarily rounding them. For each integer variable with
23 * fractional solution value, the heuristic calculates bounds for both possible rounding directions such that the
24 * obtained solution stays LP-feasible. The solution value is then shifted by the corresponding bound into the direction
