New record set for snake-in-the-box problem with novel algorithms

By PulseAugur Editorial · [1 sources] ·

Researchers have established a new record for the snake-in-the-box problem, finding a length-191 snake in dimension n=9. This discovery improves upon a previous record of 190 that had stood for 14 years and also sets new lower bounds for dimensions 10-13. The breakthrough was achieved through the introduction of "snakepits" to expand the search space and a novel algorithm called Beam Anchor, which utilizes search-supervised learned construction to find multiple variations of the length-190 snakes.

    New Snake-in-the-Box Records via Snakepit Surgery and Learned Construction

    arXiv:2607.15270v3 Announce Type: cross Abstract: The snake-in-the-box problem asks for a longest induced path in the hypercube graph $Q_n$. We find a length-191 snake in dimension $n=9$, the lowest dimension where the maximum is unknown, improving the previous record of 190 that…
