  3. Statistical Decision Theory

Solving Problems by Searching #

Search in Complex Environments #

  • If the agent has no additional information—that is, if the environment is unknown—then the agent can do no better than to execute one of the actions at random.
  • If the model is correct, then once the agent has found a solution, it can close its eyes because the solution is guaranteed to lead to the goal. Control theorists call this an open-loop system: ignoring the percepts breaks the loop between agent and environment. If there is a chance that the model is incorrect, or the environment is nondeterministic, then the agent would be safer using a closed-loop approach that monitors the percepts
