1. The program accepts only binary relationships. For example, Plays(Player,Team) to denote that a player plays for a team. But you cannnot have a relation Plays(Player,Team,Match) to denote that a player plays for a team in a match. This is not a fundamental limitation; we just haven't gotten around to extending the program to general arities.
  2. Discrete Attributes can have at most 10 possible values. The Tetrad Bayes learner requires their users to specify the maximum number of possible values; we set it at 10 to save our users from having to specify another parameter.
