Macroscopic Structures Emerging from the Interactions of Simple Replicators

Authors: Perry W. Swanborough

A macroscopic view of Langton (1984) and Byl (1989) self-replicating loops has facilitated their representation by oriented states of single cells. In this work, the single-cell representation of the loop replicator is adapted to facilitate a wide variety of interactions identifiable by observation of the dynamics of arbitrary spatial distributions of many replicator copies. Dynamic loops of periods greater than the four-step rotation cycle of the orientated state were observed, and examples with periods of 20 and 12 are shown. The paper includes some discussion of irreversibility in both computation and biology, with recognition of the problem of deriving concrete conclusions about abiogenesis and pre-LUCA biology from speculative preliminary abstraction.
