Benchmark

non-incremental/QF_ABV/platania/bellford/bf20.c.smt2 

The benchmarks come from Bounded Model Checking of software. Each of them is a
family of formulae obtained during the check of a program and is parametric in
the size of the arrays. They actually don't involve Uninterpreted Functions but
just Arrays and Bitvectors.

This family contains formulae modeling the Bellmann Ford algorithm on a graph
of 5 nodes and N (the increasing parameter) arcs.
