We consider effect of declaration on emergence of cooperation in demographic Donor-Recipient game. Players are initially randomly distributed in square lattice of cells. In each period, players move locally to random cell in neighbors or globally to random unoccupied cell in the whole lattice, and play multiple games against local neighbors or against(More)
The present paper deals with a continuous-time sequential allocation problem in the following context. Consider an m-unit parallel system in which each unit stochastically deteriorates with age. When the system breaks down, all or some failed units are replaced with new units or the failed system is left as it is until the end of planning horizon. As a(More)
—We consider the effect of tags and their reputation on the emergence of cooperation in demographic Donor-Recipient game. Players are initially randomly distributed in square lattice of cells. In each period, players move locally to random cell in neighbors or globally to random unoccupied cell in the whole lattice, and play multiple games against local(More)
We consider an interaction between a donor and a recipient where the actions of a donor produce multiple results to the recipient. There are Optimists and Pessimists who focus on the best and worst outcomes among them as a recipient of the interaction, respectively, and they try to reflect on their experience in their next action as a donor. What is the(More)
