Integrating emotion-imitating into strategy learning improves cooperation in social dilemmas with extortion

Effect of heterogeneous investment induced by payoff and emotion on cooperation in public goods games by considering memory decline effects

“…Szolnoki et al [32,33] studied a pioneering work about emotion and claimed that a player shows envy to a more successful opponent and sympathy to a less successful opponent. Quan et al [34] proposed an emotion-imitating rule for strategy updating and found that it significantly boosts cooperation level in social dilemmas with extortion. Wang et al [35], Ji et al [34], and Xie et al [36] found that the diversity of the emotion dramatically increases the cooperation level and produces a high level of social welfare.…”

Wang et al [35], Ji et al [34], and Xie et al [36] found that the diversity of the emotion dramatically increases the cooperation level and produces a high level of social welfare. These investigations regarded the emotion of players toward their opponents as homogeneous, which is unsuitable for emotional investments because a player's emotions are also different when facing diverse opponents.…”

Conditional investment strategy in evolutionary trust games with repeated group interactions

“…Although there were attempts for enhancing the level of trust from different aspects, we notice that these studies are usually carried out in the framework of one-shot interaction, to our knowledge [8,9,16,24,26]. Indeed, real interactions are repeated rather than the one-shot interaction assumed above [11,10,30,33,28]. For example, we are likely to interact frequently with friends, co-workers, and economic partners in our daily life.…”

Impact of reputation-based switching strategy between punishment and social exclusion on the evolution of cooperation in the spatial public goods game

“…The public goods game (PGG) is one of the paradigms used to explore cooperative behaviors in multi-player interactions [11]. Many mechanisms based on PGG to promote the evolution of cooperative behaviors have been proposed [10,[12][13][14][15][16][17][18]. Recently, the evolutionary dynamics of PGG in social systems with higher-order interactions and its effects on the evolution of cooperation have also been explored [19].…”
