Various equilibrium concepts such as Nash, general meta-rationality (GMR), sequential stability (SEQ), and so on, help anticipate different results of a conflict. In the Prisoner Dilemma (PD) game, for example, some players can choose not to cooperate (just as the Nash equilibrium anticipates) or they can choose to cooperate; perhaps this is becaus...

Mainstream approaches to analyzing innovation systems are based on statistical methods, use standard sets of indicators, and are typically deployed to measure and classify innovation performance. As they are not based on decision-theoretic approaches that involve the multiple agents that are usually embedded in innovation systems, conventional appr...

Prospect Theory provides a broad and solid frame of reference for modeling the decision making of rational agents. In the early 1990s, the structure of Prospect Theory was used to propose a method to aid a multicriteria decision based on the process of paired comparison. The research reported in this article has empirically assessed the adherence o...

Nash equilibrium is an important concept for studying human behavior in group decision making process. Given the complexity of finding Nash equilibria, computational tools are necessary to find them.

The equilibrium proposed by Nash provides a basis from which group decisions can be selected. This kind of choice establishes a situation in which none of the participants will have any incentive to change their strategy if they are acting rationally, which is the major assumption of game theory. Leoneti proposed a utility function that allows mult...
