Breaking Generator Symmetry
George Katsirelos, Nina Narodytska, Toby Walsh
Dealing with large numbers of symmetries is often problematic. One solution is to focus on just symmetries that generate the symmetry group. Whilst there are special cases where br…
The Weighted CFG Constraint
George Katsirelos, Nina Narodytska, Toby Walsh
We introduce the weighted CFG constraint and propose a propagation algorithm that enforces domain consistency in time. We show that this algorithm can be decomposed int…
Flow-Based Propagators for the SEQUENCE and Related Global Constraints
Michael J. Maher, Nina Narodytska, Claude-Guy Quimper +1
We propose new filtering algorithms for the SEQUENCE constraint and some extensions of the SEQUENCE constraint based on network flows. We enforce domain consistency on the SEQUENCE…
Elicitation strategies for fuzzy constraint problems with missing preferences: algorithms and experimental studies
Mirco Gelain, Maria Pini, Francesca Rossi +2
Fuzzy constraints are a popular approach to handle preferences and over-constrained problems in scenarios where one needs to be cautious, such as in medical or space applications.…
Manipulation and gender neutrality in stable marriage procedures
Maria Pini, Francesca Rossi, Brent Venable +1
The stable marriage problem is a well-known problem of matching men to women so that no man and woman who are not married to each other both prefer each other. Such a problem has a…
Symmetries of Symmetry Breaking Constraints
George Katsirelos, Toby Walsh
Symmetry is an important feature of many constraint programs. We show that any symmetry acting on a set of symmetry breaking constraints can be used to break symmetry. Different sy…
