Partial and Fuzzy Constraint Satisfaction to Support Coalition Formation

Petros Belsis, Stefanos Gritzalis, Sokratis K. Katsikas
2007 Electronical Notes in Theoretical Computer Science  
In contrast to monolithic (crisp) constraint satisfaction techniques, we extend the applicability of constraints for access control, by examining soft constraints and partial constraint satisfaction.  ...  Due to the presence of conflicting requirements and specifications, the policy negotiation and policy merging processes call for the use of efficient techniques to resolve ambiguities.  ...  In order to support coalition formation and to resolve conflicts, a model based on partial constraint satisfaction has been introduced.  ...

Simultaneous Resource Accumulation and Payoff Allocation: A Cooperative Fuzzy Game Approach

Surajit Borkotokey, Rupok Neog, Qiang Zhang
2018 Advances in Fuzzy Systems  
We develop a simultaneous resource accumulation and payoff allocation algorithm under the framework of a cooperative fuzzy game that builds on our earlier work on the role of satisfaction in resource accumulation  ...  Moreover we characterize our solution using two properties: asymptotic fairness and efficiency. Our model includes a suitable penalty function to refrain players from unreasonable demands.  ...  Acknowledgments The work is partially supported by UKIERI [184-15/2017(IC)].  ...

Finding partitions of arguments with Dung's properties via SCSPs

Stefano Bistarelli, Paola Campli, Francesco Santini
2011 Proceedings of the 2011 ACM Symposium on Applied Computing - SAC '11  
Some problems in weighted argumentation are NP complete; we use (soft) constraints as a formal approach to reason about coalitions and to model all these problems in the same framework.  ...  To implement this mapping and practically find its solutions we use JaCoP, a Java constraint solver, and we test the code over a small-world network.  ...  Such a structure is similar to a semiring (see Sec. 3). Problems defined according to the semiring-based framework are called Soft Constraint Satisfaction Problems (SCSPs) [4, 3, 18] .  ...
