Shaping and Trimming Branch-and-bound Trees
Philipp M. Christophel, Imre Pólik
We present a new branch-and-bound type search method for mixed integer linear optimization problems based on the concept of offshoots (introduced in this paper). While similar to a…

New symmetries in mixed-integer linear optimization: Symmetry heuristics and complement-based symmetries
Philipp M. Christophel, Menal Güzelsoy, Imre Pólik
We present two novel applications of symmetries for mixed-integer linear programming. First we propose two variants of a new heuristic to improve the objective value of a feasible…
