Deductive inference is usually regarded as being “tautological” or “analytical”: the information conveyed by the conclusion is contained in the information conveyed by the premises. This idea, however, clashes with the undecidability of first-order logic and with the (likely) intractability of Boolean logic. In this article, we address the problem both from the semantic and the proof-theoretical point...
A number of inherent weaknesses are identified with using addresses to reference values. These weaknesses negatively impact on the development of architectures using addressing. It is proposed that values should be referenced using semantic information retained with the value. A computational model based on simple arithmetic and natural deduction is presented that illustrates how such a referencing...
