LP diving heuristic that chooses fixings w.r.t. the matrix coefficients.
Diving heuristic: Iteratively fixes some fractional variable and resolves the LP-relaxation, thereby simulating a depth-first-search in the tree. Coefficient Diving chooses the variable with the fewest locking number in any direction and rounds it into this direction. One-level backtracking is applied: If the LP gets infeasible, the last fixing is undone, and the opposite fixing is tried. If this is infeasible, too, the procedure aborts.
