Jünger, Michael (ed.) et al., Facets of combinatorial optimization. Festschrift for Martin Grötschel on the occasion of his 65th birthday. Berlin: Springer (ISBN 978-3-642-38188-1/hbk; 978-3-642-38189-8/ebook). 449-481 (2013).

Summary: Back in 2001, R. E. Bixby et al. [in: The sharpest cut. The impact of Manfred Padberg and his work. Papers from the workshop in honor of Manfred Padberg’s 60th birthday, Berlin, Germany, October 11–13, 2001. Philadelphia, PA: Society for Industrial and Applied Mathematics (SIAM). Philadelphia, PA: MPS, Mathematical Programming Society. 309–325 (2004; Zbl 1152.90542)] provided an analysis of the performance impact of the main mixed integer programming features and improvements up to CPLEX 8.0 for a workshop in honor of Manfred Padberg’s 60th birthday, which was later published in a Festschrift edited by M. Grötschel (ed.) [The sharpest cut. The impact of Manfred Padberg and his work. Papers from the workshop in honor of Manfred Padberg’s 60th birthday, Berlin, Germany, October 11–13, 2001. Philadelphia, PA: Society for Industrial and Applied Mathematics (SIAM). Philadelphia, PA: MPS, Mathematical Programming Society (2004; Zbl 1050.90003)]. Now, 12 years later, Grötschel’s own 65th birthday celebration seems to be the ideal opportunity to provide an update on the state of affairs.{

}In this paper, we outline an unbiased way to analyze benchmark results and apply this scheme to assess the contribution of the main components in CPLEX 12.5 to the ability to solve MIPs. We highlight some of the more recent features, in particular the deterministic parallel optimizer.

For the entire collection see [Zbl 1282.90010].
