Bundle Event Structures and CCSP
We investigate which event structures can be denoted by means of closed CCS ∪ CSP expressions. Working up to isomorphism we find that • all denotable event structures are bund...

Metric Semantics for True Concurrent Real Time
This paper investigates the use of a complete metric space framework for providing denotational semantics to a real-time process algebra. The study is carried out in a non-interlea...

On Extending Symmetry Sets for 2D Shapes
Many attempts have been made to represent families of 2D shapes in a simpler way. These approaches lead to so-called structures as the Symmetry Set (SS) and a subset of it, the Med...

Tilings as a programming exercise
We investigate the problem of producing symmetric tilings by programs in a uniform way. By this, we mean that the construction of a tiling should be parameterized by the geometric...

Formulation symmetries in circle packing
The performance of Branch-and-Bound algorithms is severely impaired by the presence of symmetric optima in a given problem. We describe a method for the automatic detection of for...
