“…These replicators are reminiscent of the CA 'worms' of [7] 4 with spare atoms playing the role of the grid of cells. See also [11] for related work that additionally describes the potential benefits of a 'fluidity of site arrangements' that AChems offer over CA.…”

We describe some results submitted by users of the Organic Builder, a Java applet where the rules of an artificial chemistry can be chosen in order to achieve a desired behaviour. While initially intended as a set of challenges to be tackled, as a game, the users experimented with the system far beyond this and discovered several novel forms of self-replicators. When searching for a system with certain properties such as self-replication, making the system accessible to the public through a website is an unusual but effective way of making scientific discoveries, credit for which must go to the users themselves for their tireless experimentation and innovation.

“…is constructed by introducing self-inspection to further increase the degrees of freedom. The cellular space of SR 8 [12] has a ribbon-shaped structure called a worm or an annular structure called a loop. First, these shapes are encoded in genes.…”

“…On the other hand, Langton [9] introduced the novel criterion of two different ways to handle the hereditary information stored in the configuration as interpreted and uninterpreted, and accordingly constructed a simple selfreproducing loop based on Codd's [3] eight-state model. This was followed by the publication of several variations of Langton's loop and simplified models [1,5,[12][13][14][15]. Of these, SR 8 and SR 12 of Ibáñez and colleagues [5] and Morita and Imai [12,13] also employ the concept of self-inspection.…”

By automatically encoding the shape, these techniques perform self-reproduction without separately maintaining all of the hereditary information.…”

SUMMARYWe have designed self-reproducing cellular automata based on two-and three-dimensional self-inspection, and emphasized the importance of simulating the intercellular transitions during the design phase. In particular, to understand the behavior in three dimensions, viewing the video image is essential. In this paper, we present videos generated by a simulation tool we built and demonstrate the operation according to the designs of previously designed self-reproducing cellular automata.

“…The first dealt with the implementation of universal constructors, following the approach of von Neumann's self-reproducing automaton, traceable to a series of studies of the 50s and 60s [2,5,6]. Subsequently, research of a minimum system capable of nontrivial reproduction took place, thanks to a series of studies started by Langton [3], which set off other similar works [7][8][9][10]. During the 90s, many studies provided other computing capabilities of the self-reproducers [11,12].…”

In order to understand the interplay among information, genetic instructions, and phenotypic variations, self-reproducers discovered in two-dimensional cellular automata are considered as proto-organisms, which undergo to mutations as they were in a real environmental situation. We realized a computational model through which we have been able to discover the genetic map of the self-reproducers and the networks they use. Identifying in these maps sets of different functional genes, we found that mutations in the genetic sequences could affect both external shapes and behavior of the self-reproducers, thus realizing different life-like strategies in the evolution process. The results highlight that some strategies evolution uses in selecting organisms
