Nontrivial Hamiltonian Cycle on 2D grid.

Revision en2, by Soul_Full_Of_Thunder, 2020-07-05 23:41:10

Two days ago, one of my friends (Danylo99) told me about a cool problem from a recent SIT contest. The goal was to find a nontrivial cycle that visits all cells on a 2D grid with even sides.

I thought it would be interesting to visualize the results.

Here is a slightly larger one. If anyone knows other approaches, please share :)

By the way, I also made a video of what's going on inside the algorithm.

Hope you all have a great day!
