%description
Iterated race is an extension of the Iterated F-race method for the
automatic configuration of optimization algorithms, that is, (offline)
tuning their parameters by finding the most appropriate settings given a
set of instances of an optimization problem. M. López-Ibáñez, J.
Dubois-Lacoste, L. Pérez Cáceres, T. Stützle, and M. Birattari (2016)
