Parameterized Complexity Results in Symmetry Breaking
Abstract. Symmetry is a common feature of many combinatorial problems. Unfortunately eliminating all symmetry from a problem is often computationally intractable. This paper argues...

Frameworks Symmetry and Rigidity
Symmetry equations are obtained for the rigidity matrix of a bar-joint framework in Rd . These form the basis for a short proof of the FowlerGuest symmetry group generalisation of...

Closed-form Blending of Local Symmetries
We present a closed-form solution for the symmetrization problem, solving for the optimal deformation that reconciles a set of local bilateral symmetries. Given as input a set of ...
