A declarative programming language has two kinds of semantics. The tract helps in reasoning about speci cations and correctness, while an operational semantics determines the mann...
We introduce an LTL-like logic with atomic formulae built over a constraint language interpreting variables in Z. The constraint language includes periodicity constraints, comparis...
Equilibrium logic, introduced by David Pearce, extends the concept of an answer set from logic programs to arbitrary sets of formulas. Logic programs correspond to the special case...
Abstract. We extend cc to allow the specification of a discrete probability distribution for random variables. We demonstrate the expressiveness of pcc by synthesizing combinators...
Abstract. We introduce a compositional characterization of the operational semantics of equational Horn programs. Then we show that this semantics and the standard operational sema...
