Faster Symmetry Breaking Constraints for Abstract Structures

AAAI 2026technical

In constraint programming and related paradigms, a modeller specifies their problem in a modelling language for a solver to search and return its solution(s). Using high-level modelling languages such as ESSENCE, a modeller may express their problems in terms of abstract structures. These are struct

Conjure: Automatic Generation of Constraint Models from Problem Specifications (Extended Abstract)

IJCAI 2023poster

When solving a combinatorial problem, the formulation or model of the problem is critical to the efficiency of the solver. Automating the modelling process has long been of interest given the expertise and time required to develop an effective model of a particular problem. We describe a method to a…

Learning When to Use Automatic Tabulation in Constraint Model Reformulation

IJCAI 2023poster

Combinatorial optimisation has numerous practical applications, such as planning, logistics, or circuit design. Problems such as these can be solved by approaches such as Boolean Satisfiability (SAT) or Constraint Programming (CP). Solver performance is affected significantly by the model chosen to…
