Symmetry integrated region-based image segmentation
Symmetry is an important cue for machine perception that involves high-level knowledge of image components. Unlike most of the previous research that only computes symmetry in an ...

Six Ways of Integrating Symmetries within Non-overlapping Constraints
Abstract: This paper introduces six ways for handling a chain of lexicographic ordering constraint between the origins of identical orthotopes (e.g., rectangles, boxes, hyper-recta...

Tractable Symmetry Breaking for CSPs with Interchangeable Values
Symmetry breaking in CSPs has attracted consid­ erable attention in recent years. Various general schemes have been proposed to eliminate sym­ metries during search. In general,...

Hybrid Set Domains to Strengthen Constraint Propagation and Reduce Symmetries
In CP literature combinatorial design problems such as sport scheduling, Steiner systems, error-correcting codes and more, are typically solved using Finite Domain (FD) models desp...

Constraint Symmetry and Solution Symmetry
Symmetry in constraint satisfaction problems (CSPs) has been considered in two fundamentally different ways: as an operation preserving the solutions of a CSP instance, or as an o...
