Symmetry feature in content-based image retrieval
In this paper, we first apply the theory of wallpaper groups to natural images and extract a novel feature to depict the symmetry property of natural images. The original proposed...

Language-Level Symmetry Reduction for Probabilistic Model Checking
—Symmetry reduction is a technique for combating state-space explosion in model checking. The generic representatives approach to symmetry reduction uses a language-level transla...

Automatic Symmetry Detection for Promela
We introduce a specification language, Promela-Lite, which captures the essential features of Promela but which, unlike Promela, has a formally defined semantics. We show how we ca...

A Discrete Geometric Optimal Control Framework for Systems with Symmetries
— This paper studies the optimal motion control of mechanical systems through a discrete geometric approach. At the core of our formulation is a discrete Lagrange-d’AlembertPon...

Symmetry Breaking as a Prelude to Implied Constraints: A Constraint Modelling Pattern
Finite-domain constraint programming can be used to solve a wide range of problems by first modelling the problem as a set of constraints that characterise the problem’s solutio...
