Evolutionary Game Theory Network Models: PDG vs SG Structures #1381231 (License: Personal Use)

This diagram displays five distinct network topologies used in evolutionary game theory: two Prisoner’s Dilemma Game (PDG) variants (a-1, a-2) and three Snowdrift Game (SG) variants (b-1, b-2, b-3). Each node represents an agent-red for cooperators, blue for defectors-with edges indicating strategic interactions; central yellow ovals denote pairwise focal interactions between agents i and j. The layout highlights how structural differences affect cooperation emergence under varying payoff matrices.

Used in academic papers, lecture slides, or educational web pages on evolutionary game theory, complex networks, or behavioral economics; targets researchers, graduate students, and educators seeking visual intuition for strategic interaction models.
