New research proves theoretical limits for quantum game equilibrium finding

By PulseAugur Editorial · [1 sources] ·

This research paper investigates the theoretical limits of optimistic matrix mirror-prox algorithms for finding approximate Nash equilibria in quantum zero-sum games. The authors establish a lower bound of $\Omega(1/\varepsilon)$ for the average-iterate convergence rate, indicating that the dependence on accuracy is tight. They also construct specific games to demonstrate that optimistic gradient descent-ascent and optimistic matrix multiplicative weights updates can exhibit polynomial convergence rates for their last iterates, rather than exponential.

    Average-and Last-Iterate Lower Bounds for Optimistic Matrix Mirror-Prox in Quantum Zero-Sum Games

    arXiv:2609.38835v1 Announce Type: cross Abstract: Optimistic matrix mirror-prox (OMMP) computes $\epsilon$-approximate Nash equilibria in quantum zero-sum games with an $O(1/\varepsilon)$ average-iterate guarantee [arXiv:2311.10859]. We investigate whether this dependence on accu…
