Reasoning about string variables, in particular program inputs, is an important aspect of many program analyses and testing frameworks. Program inputs invariably arrive as strings...
Incorporating the possibility of attaching attributes to variables in a logic programming system has been shown to allow the addition of general constraint solving capabilities to...

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 co...
Using a glass-box theory of finite domain constraints, FD, we show how the entailment of user-defined constraints can be expressed by antimonotone FD constraints. We also provide a...
The semantics of constraint logic programming languages with coroutining facilities (\freeze," suspension, residuation, etc.) cannot be fully declarative; thus, an operationa...
