aima.core.search.online.OnlineSearchProblem
Artificial Intelligence A Modern Approach (3rd Edition): page 147.

An online search problem must be solved by an agent executing actions, rather than by pure computation. We assume a deterministic and fully observable environment (Chapter 17 relaxes these assumptions), but we stipulate that the agent knows only the following:
- ACTIONS(s), which returns a list of actions allowed in state s;
- The step-cost function c(s, a, s') - note that this cannot be used until the agent knows that s' is the outcome; and
- GOAL-TEST(s).
