Percept Action Model

Situation calculus

true(s,N) :- does(P,a,M) & true(r,M) & succ(M,N)

true(r,N) :- sees(P,p,N) & true(q,M)

Notes:

Always possible to simulate with another player

In current development plan but not scheduled

No plans at present for probabilistic track

(though players may use probabilities in playing)

Unlike GGP, players donot receive complete rules at runtime, only definitions of possible percepts and actions.

On the other hand, players do receive multiple legal game histories.

Goal of the player is to induce the rules and then play the game effectively. Alternatively, it may skip straight to learning Q-functions. Interesting to see which approach works best.

Player is provided

Enumeration/definition of percepts and actions

One of the percepts is a “happiness” percept

Performance measure is aggregate over steps

Discussion

Bit more difficult

Gets at issues of conceptualization of world
