Book DetailsDIMACS  Series in Discrete Mathematics and Theoretical Computer ScienceVolume: 12; 1993; 592 ppMSC: Primary 68; 90;
Interest has grown recently in the application of computational and statistical tools to problems in the analysis of algorithms. In many algorithmic domains worstcase bounds are too pessimistic and tractable probabilistic models too unrealistic to provide meaningful predictions of practical algorithmic performance. Experimental approaches can provide knowledge where purely analytical methods fail and can provide insights to motivate and guide deeper analytical results. The DIMACS Implementation Challenge was organized to encourage experimental work in the area of network flows and matchings. Participants at sites in the U.S., Europe, and Japan undertook projects between November 1990 and August 1991 to test and evaluate algorithms for these problems. The Challenge culminated in a threeday workshop held in October 1991 at DIMACS. This volume contains the revised and refereed versions of twentytwo of the papers presented at the workshop, along with supplemental material about the Challenge and the Workshop.
