Hello everyone,

I'm very pleased to announce that my paper on Superposition with
Structural Induction has been accepted at Frocos 2017.
The current (almost final) version can be found at
https://cedeela.fr/~simon/files/frocos_17_paper.pdf .

Many thanks to Josef Urban, Giles Reger and Mathias Fleury for their
comments (and of course to Jasmin).

To Giles: I forgot to answer your question about AvatarSimp. The thing
is, I did not implement the full AVATAR calculus (no freezing/unfreezing
of clauses based on the model), for lack of time. Therefore the prover
explores all branches "at the same time". In this setting, AvatarSimp
allows a closed branch to be effectively pruned (killing clauses in the

Also, ground coversets are built by a kind of extension of
Skolemization: for a variable of type nat, I generate {0, s(n)} where n
is a fresh Skolem.
