The Pull-Tab Transformation

We present a new approach to the execution of functional logic programs. Our approach relies on definitional trees for the deterministic portions of a computation and on a graph transformation, called pull-tab, for the non-deterministic portions. This transformation moves, one level at a time, non-deterministic choices towards the root of the graph representing the state of a computation. With ...

Coevolution of Machines and Tapes

A problem of self-referential paradox and self-reproduction is discussed in a network model of machines and tapes. A tape consists of a bit string, encoding function of a machine. Tapes are replicated when it is attached by an adequate machine. Generally, a tape is replicated but it may be di erent from the original one. In this paper, external noise evolves diversity in a system. New reaction ...
