New algorithms tackle equilibria in concurrent stopping games

Researchers have developed new algorithms for analyzing equilibria in concurrent stopping games, a model used for multi-agent systems. The constrained existence problem for Nash equilibria in these games is undecidable, even for simpler turn-based scenarios. The study proposes an approximate solution by considering ε-Nash equilibria, which is computationally intensive but polynomial in the bit-size of ε. Additionally, the research explores extreme risk-sensitive equilibria (XRSE), where players consider worst-case payoffs, and finds the constrained existence problem for XRSE to be NP-complete in concurrent games.
