We study two group theoretic problems, Group Intersection and Double Coset Membership, in the setting of black-box groups, where Double Coset Membership generalizes a set of problems, including Group Membership, Group Factorization, and Coset Intersection. No polynomial-time classical algorithms are known for these problems. We show that for solvable groups, there exist efficient quantum algori...

To meet the requirements of dynamic and uncertain environments, Sensible Agents are capable of dynamically changing their organizational structures by modifying their roles, which are represented as their autonomy levels (e.g. command-driven, consensus, locally autonomous, and master). Maintaining correct knowledge of the current group membership is essential for Sensible Agents since such info...

In distributed systems, a group of computer should continue to do cooperation in order to finish some jobs. In such a system, a group membership protocol is especially practical and important elements to provide processes in a group with a consistent common knowledge about the membership of the group. Whenever a membership change occurs, processes should agree on which of them should do to acco...

This paper presents a novel method to authenticate an individual’s membership in a group without revealing the individual’s identity and without restricting how the member of the group may be changed. It has the ability to authenticate membership and is robust to cope with the variations of both the group size and the group member of membership.

Derecho is an RDMA-based distributed computing framework that unifies group membership management, consistent data replication and persistence. Applications are structured as top-level groups which can be split into subgroups or automatically sharded in a regular manner. To preserve membership invariants, Derecho adjusts subgroup membership as parent-group membership evolves. The resulting mix ...

Abstract Background Juvenile delinquents constitute a heterogeneous group, which complicates decision-making based on risk assessment. Various psychosocial factors have been used to define clinically relevant subgroups of juvenile offenders, while neurobiological variables not yet integrated in this context. Moreover, translation group differences individual assessment has proven difficult. We ...

This research established an assessment mechanism for university library's micro services from the perspectives of user, information and technology. First, it proposed a Group AHP method based on clustering technique to construct judgment matrix evaluate target system. Second, conducted empirical analysis 8 representative library WeChat accounts with fuzzy membership degree function. paper prov...
