in my opinion its better to have more nodes then to have less.

i'm agree with stefan, to think about a rectangle-like navigation, but i think its very difficult, but the best is it, because of natural movement.

maybe it can be realized like to cut everwhere anyone can walk so walkable-rectangles can cut out of a big one (the whole map). so you know after a while where you can walk. the good thing is, if a bot run across an area, and there is a box in the middel, he runs against him, and can cut a new rectangle out of the big (mapsize) rectangle...

so a bot can completly selflearn.

there are 2 problems.
1- the map is 3D
2- its only my wild theory :-)
