ABSTRACT

We present some recent results  showing how the hardness of proving a parity combinatorial principle on graphs (so-called Tseitin Principle)  is a function of well-known graph structural measures like tree-width, path-width, etc. The results entail characterizations  of  several proof measures in terms of well-known  graph searching games.
