AWhat changed
Defined a class of two-player zero-sum stochastic games with state transitions and proved the existence and characterization of values for the discounted finite-state setting treated in the paper.
Scientific scope
The record is the exact 1953 PNAS paper. Repeated games, general-sum stochastic games, Markov decision processes, reinforcement-learning algorithms and later equilibrium refinements remain separate.
Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1953 PNAS paper. Repeated games, general-sum stochastic games, Markov decision processes, reinforcement-learning algorithms and later equilibrium refinements remain separate.
