Checking satisfiability of a conjunction of BDDs
Procedures for Boolean satis ability most commonly work with Conjunctive Normal Form. Powerful SAT techniques based on implications and con icts can be retained when the usual CNF...

A Study of a Positive Fragment of Path Queries: Expressiveness, Normal Form, and Minimization
We study the expressiveness of a positive fragment of path queries, denoted Path+ , on node-labeled trees documents. The expressiveness of Path+ is studied from two angles. First, ...

A New Proposal Of Quasi-Solved Form For Equality Constraint Solving
Most well-known algorithms for equational solving are based on quantifier elimination. This technique iteratively eliminates the innermost block of existential/universal quantifie...

Alembic: An Efficient Algorithm for CNF Preprocessing
Satisfiability (SAT) solvers often benefit from a preprocessing of the formula to be decided. For formulae in conjunctive normal form (CNF), subsumed clauses may be removed or par...
