Applications of this game exist in network path selection, load distribution, and network interdiction. We perform a worst case analysis of the Hedge algorithm by using an adversary, who will consistently select penalties so as to maximize the player’s loss, assuming that the adversary’s penalty budget is limited. We further explore the performance of binary penalties, and we prove that the optimum binary strategy for the adversary is to make greedy decisions.展开更多

Maritime cluster＇s evolution is an under-investigated area, with ramifications in maritime policy and business decision-making. In this paper, we study the evolutionary formation of maritime clusters, in the contemporary European blue economy context. We examine pertinent factors for the sustainable development of maritime clusters, with a strong technical, service and market innovation orientation. We merely examine the significance of legislative, financial, business networking and knowledge management related components. Qualitative empirical testing of the theoretical premises is performed for the Spanish, Italian, Greek and Cypriot cluster entities.展开更多
