What environment properties does a web crawling agent face?

  • A.Partially observable, episodic and deterministic
  • B.Partially observable, sequential and dynamic
  • C.Fully observable, episodic and static
  • D.Fully observable, deterministic and discrete

Answer: B

A crawler sees only the pages it has fetched, its choices about what to fetch affect what it can reach later, and the web changes while it works. It is also effectively multi-agent, since other crawlers and site operators respond to it. Classifying an unfamiliar task against the standard dimensions is the quickest way to see which techniques will be needed, and here it points at partial observability and sequential decision making rather than simple classification.
