Last time, we showed how to implement a navigation world full of convex, disjoint polygons; now we'll navigate it (see exercise 4.11b).
The nature of the percepts has been underspecified; in order to implement the world, for instance, we'll have to make a decision as to whether:
- The goal is always given relative to the agent; or
- the goal is only given when it is visible.
Either model has implications for search and discovery strategies.
