Coalgebraic Logic Programming : Implicit Versus Explicit Resource Handling

We compare approaches to implicit and explicit resource handling in coinductive and concurrent logic programming. We show various effects that implicit and explicit handling of resources have on implementation and semantics. In particular, we show that recently introduced coalgebraic logic programming [17] is a paradigm in which, in contrast to many other alternative systems, the aspects of logic and control are intertwined, and computational resources are handled implicitly.
