Solving string constraints lazily
Decision procedures have long been a fixture in program analysis, and reasoning about string constraints is a key element in many program analyses and testing frameworks. Recent ...

Controllability of Soft Temporal Constraint Problems
In real-life temporal scenarios, uncertainty and preferences are often essential, coexisting aspects. We present a formalism where temporal constraints with both preferences and un...

Declarative Diagnosis of Missing Answers in Constraint Functional-Logic Programming
Abstract. We present a declarative method for diagnosing missing computed answers in CFLP(D), a generic scheme for lazy Constraint Functional-Logic Programming which can be instant...

Constraint-Based Case-Based Planning Using Weighted MAX-SAT
Previous approaches to case-based planning often finds a similar plan case to a new planning problem to adapt to solve the new problem. However, in the case base, there may be some...

GAC Via Unit Propagation
In this paper we argue that an attractive and potentially very general way of achieving generalized arc consistency (GAC) on a constraint is by using unit propagation (UP) over a C...
