In this paper, an integer linear programming (ILP) model is newly introduced for the problem. Two meta-heuristics are then derived from the ILP relaxation.

Pole Przemyslaw "Psyho" Debiak won the prestigious AWTF Heuristic programming tournament. He beat not only the human participants, but also AI. He is the only human to have succeeded.

The AtCoder World Tour Finals (AWTF) is the final stage of heuristic programming competitions that focus on solving complex problems rather than trivial tasks. This year’s challenge was to build a ...

In programming, heuristics are problem-solving techniques that find good-enough solutions through shortcuts and educated guesses when perfect answers would take too long to calculate.
