We present a new algorithm to compute a subset S of vertices of a planar graph G whose removal partitions G into O(N/h) subgraphs of size O(h) and with boundary size O( h) each. ...
We propose a parallel algorithm for dynamic slicing of distributed Java programs. Given a distributed Java program, we first construct an intermediate representation in the form o...
We prove that one can express the vertex-minor relation on finite undirected graphs by formulas of monadic second-order logic (with no edge set quantification) extended with a p...
7 Irregular pyramids are made of a stack of successively reduced graphs embedded in the plane. Such pyramids are used within the segmentation framework to encode a hierarchy of pa...
We present a platform that allows a protocol researcher to specify the sequence of games from an initial protocol to a protocol where the security property under consideration can ...
