A program dependence model for concurrent logic programs and its applications
Jianjun Zhao, Jingde Cheng, K. Ushijima · 2002
The authors propose a program dependence model for concurrent logic programs. They present three types of primary program dependences named the sharing dependence, communication dependence, and unification dependence between arguments in a concurrent logic program. We formally define these primary program dependences based on mode information. We further present a dependence-based representation named the argument dependence net (ADN), which explicitly represents all primary program dependences between arguments in a concurrent logic program. We also discuss some applications of the ADN for developing software engineering tools of concurrent logic programs. Finally, we briefly introduce a program analysis system called CLPKIDS for concurrent logic programs, which is a prototype implementation of the techniques introduced.
