Scheduling in the Face of Uncertain Resource Consumption and Utility
We discuss the problem of scheduling tasks that consume uncertain amounts of a resource with known capacity and where the tasks have uncertain utility. In these circumstances, we w...

Open Constraint Optimization
Constraint satisfaction has been applied with great success in closed-world scenarios, where all options and constraints are known from the beginning and fixed. With the internet,...

Propagation Redundancy in Redundant Modelling
Combining mutually redundant models with channelling constraints increases constraint propagation. However, the extra computation efforts of the additional variables and constraint...

Box Constraint Collections for Adhoc Constraints
In this paper, we propose a new language-independent representation of adhoc constraints, called a box constraint collection. Using constructive disjunction, this representation ac...

Using the Breakout Algorithm to Identify Hard and Unsolvable Subproblems
Abstract. Local search algorithms have been very successful for solving constraint satisfaction problems (CSP). However, a major weakness has been that local search is unable to de...

Redundant Modeling for the QuasiGroup Completion Problem
Abstract. The Quasigroup Completion Problem (QCP) is a very challenging benchmark among combinatorial problems, and the focus of much recent interest in the area of constraint prog...
