Any got any pointers to fast routing algorithms? At this point I'm not looking for third party add-ons. I'm looking for a couple pages of text outlining exact steps required for implementing routing. I've seen the algorithm (dykstra's method I believe) in the back of the ArcNETWORK manual for the ArcInfo extension. I've implemented it in MB to find it can be painfully slow (I know, I know, I'll have to handle my routing in some external low level function to get speed, but hey I just playing). Anyways, anybody got any pointers to some basic routing algorithms? Any good books out there?
