On the condition of the coordination game, the enterprises may be stuck on the non-efficient equilibrium status, which becomes an important problem that must be considered on cluster supply chains. A symmetrical coordination game model is constituted to describe the competition and cooperation relationship of the same-quality manufacturers on cluster supply chains. The methods of the non-cooperation game theory and the evolutionary game theory are respectively used to analyze the model, whose parameters＇ influences under each method are then compared. It can be concluded that the analysis of the evolutionary game theory is more realistic and practical. Finally, three approaches are considered to break away from being path-dependence locked-in non-efficient status during this coordination game evolutionary process, which provide the development of cluster supply chains with an effective forecasting and Pareto optimizing method.展开更多

The swimmers were not able to communicate with each other. To win the game, the swimmer had to surface at exactly the same point as his partner. This pure coordination game was played by 81 swimmers, 43 of whom then put their decisions into practice in a 25-metre pool. The results revealed the presence of two Schelling points. One point （at 12.5 metres） was that predicted by theory and corresponded to half the maximum possible distance. The other Schelling point （at 25 metres） was practical in nature and reflected a taste for underwater swimming--even though performance （in terms of the distance swum underwater） was not relevant in this game. The results show that swimmers underestimate their water competence when they are not subjected to a competitive challenge.展开更多

We simulate the game dynamics on top of complex network topologies and approximate the fixation time distributions using a mean-field approach. We assume that there are two absorbing states. Numerically, we show that the mean fixation time is sufficient in characterizing the evolutionary timescales when network structures are close to the well-mixing condition. In contrast, the mean fixation time shows large inaccuracies when networks become sparse. The approximation accuracy is determined by the network structure, and hence by the suitability of the mean-field approach. The numerical results show good agreement with the theoretical predictions.展开更多
