## Notes

Book and year from the hosting site and contributor knowledge. Supreme Commander 2: 10x10 m sectors linked by portals; A* over the portal graph; 8-bit cost field with 255 for walls; integration field from the goal; shared flow field directions for many units; dirty sectors rebuilt by a time-sliced queue; earlier per-unit repathing on collision compounded stalls.
