note

  • A search problem consists of:
    • State space: set of possible configurations
    • Successor function: transitions between states (with actions, costs)
    • Start state and goal test
  • Solution: sequence of actions (plan) transforms start state β†’ goal state
  • Search: find a solution if it exists
  • Search problem:
    • models that abstract away the details of the environment
    • can have different state space sizes depending on the level of abstraction
    • almost always wrong but some are useful
