Deterministic problem type correct answers agent knows exactly what state it starts in and what each action does
no exogenous events (events that the agent doesn't cause)
can predict future states exactly, solution can be a sequence of actions
Non-observable problem type correct answers agent may have no idea where it is
solution (if any) must be a sequence that is conformant (guaranteed to work in all conditions)
Nondeterministic or partially observable problem type correct answers percepts provide new information about current state
solution cannot be a linear sequence of actions
- use a contingency plan or a policy
- agent's actions depend on what it observes
Problem solving agents: online vs offline correct answers online: gather knowledge as you go
offline: develop the entire solution at the start, before you ever start to execute it
Uninformed search strategies correct answers use only what's available in the problem definition
breadth first
depth first
uniform cost
evaluating search strategies correct answers completeness: does it always find an existing solution?
optimality: does it always find a least-cost solution?
time complexity: nodes generated or expanded
space complexity: nodes in memory
Measuring time and space complexity correct answers b = maximum branching factor
d = depth of the shallowest solution
m = max depth of any node
properties of breadth first search correct answers complete: yes
