Abstract Conflict-Driven Learning

19 March 2014

Time: 3:00 - 4:00pm
Venue: BR 3.02 Bancroft Road Teaching Rooms Peter Landin Building London E1 4NS

We present a lattice-theoretic generalisation of CDCL, the algorithm behind modern propositional satisfiability solvers, to reasoning in abstract domains. As an exemplar, a bit-precise decision procedure for the theory of floating-point arithmetic is shown. The talk concludes with an overview of further work, presented at POPL 2013 and 2014, and ESOP 2014.This is joint work with Martin Brain, Vijay D’Silva, Alberto Griggio and Leopold Haller.
