A parser for context free plex grammars,er for context free plex grammars. The parser is an extension of Earley‘s algorithm, which was originally developed for context free string grammars. Our parser is able to recognize not only complete structures generated by a plex grammar but also partial ones. The algorithm has been implemented and

On the complexity of optimal drawings of graphs,or (1) we propose grid embeddings of graphs and measure ”nice” by algorithmic cost measures of the embeddings, e.g., area, expansion, edge length, etc. For (2) we prove that optimal embeddings with fixed costs are NP-complete, even for binary trees. This sharpens previous NP-completeness results of

Improved self-reduction algorithms for graphs with bounded treewidth,xed upper bound on the treewidth of the graphs in the class, i.e. if there is a planar graph not in the class, then the class can be recognized in .(..) time. However, this result is non-constructive in two ways: the algorithm only decides on membership, but does not construct ‘a solution’, e.g. a l

,Toward a complete representation of graphoids in graphs — Abridged Version,n graphs. In this paper we advance towards a characterization of graphoids by families of graphs. Given two graphs . and ., let . be the set of all independencies which are implied by . and . under closure by the 5 graphoid axioms (defined in the text). We show the following results:
