Why is a table driven agent impractical for most tasks?

  • A.The table of percept sequences grows beyond any feasible size
  • B.Table lookup is slower than computing the action directly
  • C.Tables cannot represent actions that depend on the current percept
  • D.The table would have to be rewritten whenever the goal changed

Answer: A

The number of possible percept histories grows exponentially with the length of the agent's life, so even a chess playing table would need more entries than there are atoms in the observable universe. Lookup itself is fast, which is the only attraction of the design. Tables represent percept dependent behaviour perfectly well, and goal change is a separate objection. A design that is correct in principle and impossible in practice is still worth stating, because it defines what every real architecture is approximating.
