This paper deals with the isomorphism problem of directed path graphs and rooted directed path graphs. Both graph classes belong to the class of chordal graphs, and for both classes the relative complexity of the isomorphism problem is yet unknown. We prove that deciding isomorphism of directed path

We present a simple parallel algorithm for the single-source shortest path problem in planar digraphs with nonnegative real edge weights. The algorithm runs on the EREW PRAM model of parallel computation in O((n 2= +n 1&= ) log n) time, performing O(n 1+= log n) work for any 0<=<1Γ2. The strength of
The main goal of this work was to describe the basic elements constituting a specialized knowledge base in the field of paths and circuits in digraphs. This knowledge base contains commented on examples with textual and graphical descriptions, invariants, relations among invariants, and theorems. It
