We consider the problem of cutting a subset of the edges of a polyhedral manifold surface, possibly with boundary, to obtain a single topological disk, minimizing either the total...
Planning and scheduling attracts an unceasing attention of computer science community. Several research areas like Artificial Intelligence, Operations Research and Constraint Prog...
SPKI/SDSI is a proposed public key infrastructure standard that incorporates the SDSI public key infrastructure. SDSI's key innovation was the use of local names. We previous...
This paper focuses on parallel query optimization. We consider the operator problem and introduce a new class of execution strategies called Linear-Oriented Bushy Trees (LBTs). Co...
The nondeterministic information logic NIL has been introduced by Orlowska and Pawlak in 1984 as a logic for reasoning about total information systems with the similarity, the forw...
