## Computational Logic Day 2014

The goal of the Computational Logic Day is to bring together
researchers working in all areas of computational logic and closely
related topics, including but not limited to automated reasoning,
logic-based knowledge representation, constraint programming and
optimization, as well as applications. Talks this year focus
on *acyclicity*, a requirement that occurs frequently in
applications but which is cumbersome to express, e.g., using
clauses. For instance, when learning a *Bayesian network*
from data the resulting structure must be acyclic.
