,An Improvement to Chvátal and Thomassen’s Upper Bound for Oriented Diameter,ectively. For the family of 2-edge connected graphs of diameter 4, the bounds provided by Chvátal and Thomassen are 12 and 40 and no better bounds were known. By extending the method we used for diameter . graphs, along with an asymmetric extension of a technique used by Chvátal and Thomassen, we have improved this upper bound to 21.

Tianyu Feng,Zhiliang Ma,Yuan Dingmake them identical by renaming their candidates and voters, and we are interested in measuring how far are two given elections from being isomorphic. The study of such distances has just begun and in this paper we outline why we believe that it is interesting and what are the natural research directions.

Parameterized Analysis of Art Gallery and Terrain Guarding,roblems, which have, so far, received only little attention from the viewpoint of Parameterized Analysis. Moreover, we will briefly overview a few of the known positive results on the parameterized complexity of these problems.
