- If an agent acts, it may act incorrectly.
- The more it knows about the world and the effects
of its actions, the more it can plan before it acts.
- So, an agent can search a maze by moving through it.
- However, if it has already moved through it (and knows the
structure of the maze), it can plan a path.
- If planning is quicker than acting, the resulting action
may well be quicker.
- Moreover, if actions can have negative side effects, planning
may be essential.
