From Marriages to Coalitions: A Soft CSP Approach,der to define new coalition-formation principles and stability conditions. In the coalition case, we suppose the preference value as a trust score, since trust can describe the belief of a node in the capabilities of another node, in its honesty and reliability. Semiring-based soft constraints repre

An Efficient Decision Procedure for Functional Decomposable Theories Based on Dual Constraints,such as: scheduling, resource allocation, computer graphics and bio-informatics. Recently, a new property called . has been introduced and many first-order theories have been proved to be decomposable such as finite or infinite trees, rational and real numbers, linear dense order,...etc. A decision

Iterative Flattening Search on RCPSP/max Problems: Recent Developments,RCPSP/max). The algorithm is based on Iterative Flattening Search (.), an effective meta-heuristic strategy proposed over the past years for solving multi-capacity optimization scheduling problems. Given an initial solution, . iteratively applies two steps: (1)?a subset of solving decisions are rand
