A non-magical set-oriented method for Datalog (2008)
Hoi-Yee Hwang, Ho-fung Leung, Wai-chee Fu
This paper presents a new algorithm for query evaluation for datalog. The algorithm is set-oriented as it uses sets to constraint the arguments of the related rules and the subgoals generated. The...
Van Emden's incremental queries address the inadequacy of current Prolog-style querying mechanism in most logic programming systems for interactive problem-solving. In the context of constraint...

In the literature the problem of global termination detection in shared-memory asynchronous multiprocessor systems is solved by using exclusively accessible variables and locking mechanism. In this...
Towards a More Efficient Stochastic Constraint Solver (1996)
Jimmy Lee, Ho-fung Leung, Hon-wing Won
. E-GENET shows certain success on extending GENET for non-binary CSP's. However, the generic constraint representation scheme of E-GENET induces the problem of storing too many penalty values...
A Stochastic Approach to Solving Fuzzy Constraint Satisfaction Problems (1996)
this paper, we propose fuzzy EGENET by merging the idea of E-GENET and fuzzy GENET. Fuzzy E-GENET allows the representation of nonbinary FCSP's. We have built a fuzzy E-GENET simulator....
