Tarski asked whether the arithmetic identities taught in high school are complete for showing all arithmetic equations valid for the natural numbers. The answer to this question f...
Number restrictions are concept constructors that are available in almost all implemented description logic systems. However, even though there has lately been considerable effort...
Abstract. This paper reviews the history of embedded, evolvable selfreplicating structures implemented as cellular automata systems. We relate recent advances in this field to the...
Edgar Codd's 1968 design for a self-replicating cellular automata machine has never been implemented. Partly this is due to its enormous size but we have also identified four...
This paper considers the problem of adding list as a type constructor to an object-oriented data model. In particular, we are concerned with how lists in a database can be constru...
