In this paper we present a model of self-interested agents acting in an open environment, which captures the most relevant elements of agents' behaviour related to negotiation with other agents. The agent behaviour is mainly motivated by the gain they may obtain while fulfilling their goals and negotiating. Sometimes, the agents are also motivated by the(More)
The paper presents a model of heuristic negotiation between self-interested agents which allows negotiation over multiple issues of the negotiation object, comprises different types of negotiation primitives, including argument based ones, and a set of rules to conduct negotiation. In order to negotiate strategically and to adapt negotiation to different(More)
Emotions have been shown to have an important role on several human processes such as decision-making, planning, cognition, and, in particular, learning. However, many e-learning systems disregard the emotional aspects of the learning process and the impact of these aspects on the student's performance. The paper presents an intelligent agent with(More)
The paper presents a multi-agent system aiming to solve the problem of rational exploitation of natural renewable resources by self-interested agents, known also as the Tragedy of Commons. The system is geared towards a particular instance of this problem, namely the FishBanks game. The agents use genetic algorithms to build plans for fishing in several(More)
Simulation models of continuous systems are in fact discrete computational models. This is the result of applying numerical methods for integrating the differential equations generally used as mathematical models of continuous systems. Under such conditions the values of all variables in the simulation model are computed for discrete values of the(More)
