| The East-West Challenge problem has been proposed by Ryszard Michalski [Michalski 77], the task is to discover simple rules that distinguish examples of the Eastbound trains from those heading in the opposite direction. An example of such a rule is "If a train has a long closed car with more than one window, then it is heading west.". This problem has numerous variants depending on the initial description of considered examples, several of them have been presented by [Michie et al. 94] as a challenge to the international computing community in the form of a competition with the deadline early in 1995.
This entry has 3 parts: * The Challenge files describe the competition and contain all the material that was made available to the competitors. * The Results provide results of all the competitions, some comments on them and the winning program. * RL-ICET files describe an ILP solution by Peter Turney (full paper and the data preprocessor)
