An efficient search algorithm for partially ordered sets
Consider the problem of membership query for a given partially ordered set. We devise a greedy algorithm which can produce near-optimal search strategies. Rigorous analysis has be...

Evolutionary Search for Minimal Elements in Partially Ordered Finite Sets
The task of finding minimal elements of a partially ordered set is a generalization of the task of finding the global minimum of a real-valued function or of finding Pareto-optimal...

An Access Control Scheme for Partially Ordered Set Hierarchy with Provable Security
In a hierarchical structure, an entity has access to another if and only if the former is a superior of the later. The access control scheme for a hierarchy represented by a partia...
