The Peirce Translation and the Double Negation Shift
We develop applications of selection functions to proof theory and computational extraction of witnesses from proofs in classical analysis. The main novelty is a translation of cla...

Implementing Ordered Choice Logic Programming using Answer Set Solvers
Abstract. Ordered Choice Logic Programming (OCLP) allows for dynamic preference-based decision-making with multiple alternatives without the need for any form of negation. This com...

Splitting a Logic Program
In many cases, a logic program can be divided into two parts, so that one of them, the \bottom" part, does not refer to the predicates de ned in the \top" part. The \bot...

On the Role of Negation in Choice Logic Programs
We introduce choice logic programs as negation-free datalog programs that allow rules to have exclusive-only (possibly empty) disjunctions in the head. Such programs naturally mod...

Order and Negation as Failure
We equip ordered logic programs with negation as failure, using a simple generalization of the preferred answer set semantics for ordered programs. This extension supports a conven...
