LUPS—A language for updating logic programs

摘要

Most of the work conducted so far in the field of logic programming has focused on representing static knowledge, i.e., knowledge that does not evolve with time. To overcome this limitation, in a recent paper, the authors introduced dynamic logic programming. There, they studied and defined the declarative and operational semantics of sequences of logic programs (or dynamic logic programs). Each program in the sequence contains knowledge about some given state, where different states may, for example, represent different time periods or different sets of priorities.
