The logic programming language framework Kernel Andorra Prolog is de ned by a formal computation model. In Kernel Andorra Prolog, general combinations of concurrent reactive langu...
We present a framework for encoding planning problems in logic programs with negation as failure, having computational e ciency as our major consideration. In order to accomplish o...
We are interested in semantical underpinnings for existing approaches to preference handling in extended logic programming (within the framework of answer set programming). As a s...
The importance of temporal representation and reasoning is well known to the database community. Examples of such significance are the languages TSQL2 and its follow up, SQL/Tempo...
