Compactly generating all satisfying truth assignments of a Horn formula

As instance of an overarching principle of exclusion an algorithm is presented that compactly (thus not one by one) generates all models of a Horn formula. The principle of exclusion can be adapted to generate only the models of weight $k$. We compare and contrast it with constraint programming, $0,1$ integer programming, and binary decision diagrams.Comment: Considerably improves upon the readibility of the previous versio
