Webgames with speciﬁc structures (e.g., polymatrix games (Cai and Daskalakis 2011)), or there are no theoretical guarantees at all (e.g., the algorithm in Brown and Sandholm (2024)). Finding and playing NEs in multiplayer games is difﬁcult due to the following two reasons. First, computing NEs is PPAD-complete even for three-player zero-sum ... Web2.1 Network Zero-Sum Games with Charges A graphical polymatrix game is defined by an undirected graph G = (V,E), where V corresponds to the set of agents and where edges correspond to bimatrix games between the endpoints/agents. We denote by Si the set of strategies of agent i. We denote the bimatrix game on edge (i,k) ∈E via a pair of payoff ...

These games merge two classical concepts, two-player games and networks. In a polymatrix game, each player corresponds to a node in a network, and each edge encodes a two-player game between the two endpoints of the edge. A player’s payo is the sum of her payo s across
