First-order probabilistic models are recognized as efficient frameworks to represent several realworld problems: they combine the expressive power of first-order logic, which serv...
We modify the reflection method to enable it to deal with partial functions like division. The idea behind reflection is to program a tactic for a theorem prover not in the impleme...
In this paper we propose a version of default logic with the following two properties: (1) defaults with mutually inconsistent justications are never used together in constructing ...
