A Novel Approach For Detecting Symmetries in CSP Models
Abstract. While several powerful methods exist for automatically detecting symmetries in instances of constraint satisfaction problems (CSPs), current methods for detecting symmetr...

Exploiting Problem Symmetries in State-Based Planners
Previous research in Artificial Intelligence has identified the possibility of simplifying planning problems via the identification and exploitation of symmetries. We advance t...

Using conjugate symmetries to enhance gate-level simulations
State machine based simulation of Boolean functions is substantially faster if the function being simulated is symmetric. Unfortunately function symmetries are comparatively rare....

Rotation symmetry group detection via frequency analysis of frieze-expansions
We present a novel and effective algorithm for rotation symmetry group detection from real-world images. We propose a frieze-expansion method that transforms rotation symmetry gro...

Skewed Rotation Symmetry Group Detection
—We present a novel and effective algorithm for affinely skewed rotation symmetry group detection from real-world images. We define a complete skewed rotation symmetry detectio...
