30 * Diving heuristic: Iteratively fixes some fractional variable and resolves the LP-relaxation, thereby simulating a
31 * depth-first-search in the tree. Pseudocost Diving chooses the variable with the smallest ratio of estimated objective
32 * increase if rounding to either direction. If the variable is significantly different from its root LP vlaue, it will
33 * be rounded into the direction it developed (see @ref heur_linesearchdiving.h), if it is close to an integral point,
34 * it will be rounded to that one, otherwise it will be rounded into the direction of lower pseudocosts. One-level
35 * backtracking is applied: If the LP gets infeasible, the last fixing is undone, and the opposite fixing is tried. If
