Interaction between agents is one of the key factors in multi-agent societies in order to cooperatively execute complex tasks which are beyond the capability of a single agent. In the self-adaptation society, agents try to keep best neighbors around themselves. Agents use history of past iterations to evaluate their neighbors and locally modify their structural links. Main characteristics of this model are its decentralization, dynamicity and no need of external control. This research at first deals with implementing self-adaptive agent organization. Then it focuses on evaluating cooperation peers in decision making. Trust as an evaluation mechanism lies at the core of all interactions in the agent organizations. Agents build trust about a target based on their direct experiences and third party recommendations. Since agents have different perception of trust, context of decision should be taken into account. Uncertainty is one of the main contextual factors that affect agents’ decisions. The aim of the second work is helping agents have better evaluation in decision making utilizing recommendation-based trust and adaptive risk.
