Towards a Provably Resilient Scheme for Graph-Based Watermarking,ownership and therefore discouraging piracy. Graph-based watermarking schemes comprise an encoding algorithm, which translates a given number (the identifier, usually a positive integer) onto some appropriately tailored graph (the watermark), and a decoding algorithm, which extracts the original ide

The Normal Graph Conjecture for Classes of Sparse Graphs,very clique in . intersects every stable set in ...Normal graphs can be considered as closure of perfect graphs by means of co-normal products and graph entropy. Perfect graphs have been recently characterized as those graphs without odd holes and odd antiholes as induced subgraphs (Strong Perfect G

On the Parameterized Complexity of Computing Graph Bisections,ing the two vertex sets. . has been thoroughly studied in the past. However, only few results have been published that consider the parameterized complexity of this problem..We show that . is FPT w.r.t. the minimum cut size if there is an optimum bisection that cuts into a given constant number of c

Fixed-Parameter Tractability and Characterizations of Small Special Treewidth, vertex ., the bags containing . form a rooted path in decomposition tree. We resolve an open problem by Courcelle, and show that an algorithm by Bodlaender and Kloks?[7] can be modified to obtain for each fixed ., a linear time algorithm that decides if the special treewidth of a given graph is at

Equilateral L-Contact Graphs,phs, drawing connections to Schnyder realizers and canonical orders of maximally planar graphs. We show that every contact system of L’s can always be converted to an equivalent one with equilateral L’s. This can be used to show a stronger version of a result of Thomassen, namely, that every planar
