Fragment of a discussion from Talk:Path Surfing

BeepBoop uses something like a lookup table (actually a kd tree) for finding paths, but a pretty small one. Given a current velocity, desired distance to travel, and desired ending velocity it outputs a "path" (sequence of 1s/-1s/0s corresponding to calling setAhead(100/-100/0)) that approximately meets those criteria. When its surfing, BeepBoop sets the desired distance to one that will take it to a low-danger area of the wave (kind of like GoTo surfing) and sets the desired end velocity to 8, -8, or 0 randomly, which means it will try out a variety of ways of getting to that area. It then precisely predicts the looked-up paths along with the standard going forward/backward/stopping paths true surfers use.
