In this note we provide a strategic implementation of the average tree solution for zeromonotonic cycle-free graph games. That is, we propose a non-cooperative mechanism of which the unique subgame perfect equilibrium payoffs correspond to the average hierarchical outcome of the game. This mechanism takes into account that a player is only able to communicate with other players (i.e., to make p...

background the direct and indirect negative impacts of hypertension on mortality and morbidity and the deficiencies in physicians’ knowledge on its management prompted us to search for new methods of training this item. objectives in this study, 2 methods of teaching—planned lecture and cooperation—were compared in instructing hypertension to medical students. materials and methods this study w...

Understanding the emergence and maintenance of cooperation is one of the most challenging topics of our time. Evolutionary game theory offers a very flexible framework within which to address this challenge. Here we use the prisoner’s dilemma game to investigate the performance of individuals who are capable of adopting reactive strategies in communities structurally organized by means of Barab...

We study in detail the role of short-cuts in promoting the emergence of cooperation in a network of agents playing the Prisoner’s Dilemma Game (PDG). We introduce a model whose topology interpolates between the one-dimensional euclidean lattice (a ring) and the complete graph by changing the value of one parameter (the probability p to add a link between two nodes not already connected in the e...

The emergence of cooperation is a central question in evolutionary biology. Microorganisms often cooperate by producing a chemical resource (a public good) that benefits other cells. The sharing of public goods depends on their diffusion through space. Previous theory suggests that spatial structure can promote evolution of cooperation, but the diffusion of public goods introduces new phenomena...

In this paper, a cooperation network and a competition network consensus problem of multi-agent systems is study. The communication topology among agent is characterized by a directed and connected graph. And Communication between the cooperation network and the competition network through their respective leaders. The two networks can be made to reach stable and consensus by setting parameters...

Given a graph G = (V, E) with edge weights we ∈ R, the optimum cooperation problem consists in determining a partition of the graph that maximizes the sum of weights of the edges with nodes in the same class plus the number of the classes of the partition. The problem is also known in the literature as the optimum attack problem in networks. Furthermore, a relevant physics application exists. I...

Electronic commerce applications have been developed as a reaction to specific business opportunities. Their archi-tectures, so far, have been dominated by implementation concerns, without much consideration given to the cooperation model. In this paper, we describe an application independent framework to classify service interaction. It relies on four basic dimensions service topologies, coope...

The educational system of any country plays a significant role in its sustainable development and progress. However, to fulfill this function there must exist a set of guidelines and policies aimed at such development. The process of setting such a set of guidelines requires a homegrown model for development of the guidelines, and their implementation and supervision. To this end, 14 interviews...

This paper presents some results of our recent research work towards an infrastructure for Internet enabled collaborative agent systems (particularly complex industrial collaborative agent systems). Although the infrastructure and the related agent system architecture, basic communication and cooperation services, components, prototypes, mechanisms and toolkits are proposed and developed for In...
