In this paper we present two such + algorithms: one based on work dated 1991 by Sohn and + Van~Gelder; the other, due to Podelski and Rybalchenko, + dated 2004. Remarkably, while the two algorithms will + synthesize a linear ranking function under exactly the + same set of conditions, the former is mostly unknown to + the community of termination analysis and its general + applicability has never been put forward before the + present paper. In this paper we thoroughly justify both + algorithms, we prove their correctness, we compare their + worst-case complexity and experimentally evaluate their + efficiency, and we present an open-source implementation + of them that will make it very easy to include + termination-analysis capabilities in automatic program + verifiers." +} + @InProceedings{BagnaraRZH02, Author = "R.
