| 17 hours ago | comment | added | y kat | Congratulations — yes, that's the intended solution. For a computer solver, two approaches: (1) enumerate feasible tray grid patterns first (as you did, but there are more patterns actually), then search; (2) a more random/continuous method exploiting the polyomino being star-shaped (a billiard-style algorithm). | |
