We present Tiger, a visual environment to design visual language (VL) specifications based on meta models, graph grammars and layout definitions. A VL specification serves as ba...
A fractal construction shows that, for any > 0, the -skeleton of a point set can have arbitrarily large dilation: (nc ), where c is a constant depending on and going to zero ...
Phylogenetic networks are a generalization of phylogenetic trees that allow for the representation of non-treelike evolutionary events, like recombination, hybridization, or later...
Similarity of edge labeled graphs is considered in the sense of minimum squared distance between corresponding values. Vertex correspondences are established by isomorphisms if bo...
: Continuous and hybrid Petri nets can be seen as relaxation of discrete nets, in which the firing of some or of all transitions is approximated with a fluid model. Several analysi...
