The pentomino tilings of a rectangle, where every one of the 12 pentominoes appears exactly one, can be interpreted as an exact cover problem and hence enumerated with Knuth's algorithm. The repository contains
- a Python implementation of this algorithm
- a visualization of these made with Svelte
The exact cover algorithm in exactcover.py may not be optimized, but the code is incredibly short because we use Python sets (not incidence matrices) and generators - we don't need the usual "select and deselect" step.
