21 * Diving heuristic: Iteratively fixes some fractional variable and resolves the LP-relaxation, thereby simulating a 22 * depth-first-search in the tree. Vectorlength Diving chooses the variable with the smallest ratio of potential 23 * objective change and number of affected constraints and fixes it. One-level backtracking is applied: If the LP gets 24 * infeasible, the last fixings is undone, and the opposite fixing is tried. If this is infeasible, too, the procedure 28 /*---+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8----+----9----+----0----+----1----+----2*/
