The ESA Test-of-Time Award (ESA ToTA) recognizes excellent papers in algorithms research that were published in the ESA proceedings 19-21 years ago and which are still influential and stimulating for the field today. In this second year in which the award is given, papers from ESA'95 to ESA'97 were considered.

The committee nominates the following paper for the ESA ToTA 2016. The paper stands out as a classic in the algorithms field and by its excellent citation
record still relevant today.

From ESA 95-97:

Boris V. Cherkassky, Andrew V. Goldberg
Negative-cycle detection algorithms
Proceedings ESA'96, also in: Mathematical Programming 85:2 (1999) 277-311

Laudation:
The paper by Cherkassky and Goldberg deals with the problem of finding a
negative-length cycle in a network or proving that there is none. Algorithms
for this are a combination of a shortest-path algorithm and a negative-cycle
detection strategy. The authors analyse known algorithms and some new ones
and determine the best combinations. Novel instance generators are used in
this study. The paper is a model experimental paper in algorithms.
