A Versatile and Robust Model for Geometrically Complex Deformable Solids
In this paper, we present a versatile and robust model for geometrically complex deformable solids. Our approach can be applied to deformable tetrahedral meshes and to deformable ...

On the Complexity of Membership and Counting in Height-Deterministic Pushdown Automata
Abstract. While visibly pushdown languages properly generalise regular languages and are properly contained in deterministic context-free languages, the complexity of their members...

On the complex behavior of simple tag systems - An experimental approach
It is a well-know fact that apparently simple systems can give rise to complex behavior. But why exactly does a given system behave in a complex manner? There are two main approac...

Birkhoff polytopes, heat kernels and graph complexity
In this paper we use doubly stochastic matrices to establish a link between Birkhoff polytopes and heat kernels on graphs. Based on this analysis we construct a multi-dimensional ...

On the Complexity of Partial Order Properties
The recognition complexityof ordered set properties is considered, i.e.how many questions have to be asked to decide if an unknown ordered set has a prescribed property. We prove ...
