- Abstract: An explanatory model for the emergence of evolvable units must display
emerging structures that (1) preserve themselves in time (2) self-reproduce and
(3) tolerate a certain amount of variation when reproducing. To tackle this
challenge, here we introduce Combinatory Chemistry, an Algorithmic Artificial
Chemistry based on a minimalistic computational paradigm named Combinatory
Logic. The dynamics of this system comprise very few rules, it is initialised
with an elementary tabula rasa state, and features conservation laws
replicating natural resource constraints. Our experiments show that a single
run of this dynamical system with no external intervention discovers a wide
range of emergent patterns. All these structures rely on acquiring basic
constituents from the environment and decomposing them in a process that is
remarkably similar to biological metabolisms. These patterns include
autopoietic structures that maintain their organisation, recursive ones that
grow in linear chains or binary-branching trees, and most notably, patterns
able to reproduce themselves, duplicating their number at each generation.

We present a novel generative method called Response Matching (RM)
RM exploits the locality of atomic interactions, and inherently respects permutation, translation, rotation, and periodic invariances.
We demonstrate the efficiency and generalization of RM across three systems.

This paper presents a new symbolic-only method for the generation of hierarchical concept structures from complex sensory data.
The approach is based on Bateson's notion of difference as the key to the genesis of an idea or a concept.
The model is able to produce fairly rich yet human-readable conceptual representations without training.

Experiments reveal that such a system can map temporal to spatial correlation, enabling hierarchical structures to be learned from sequential data.

We use a small set of molecules to steer the pre-trained generative model towards synthesizing molecules that satisfy the given design criteria.
Our approach is agnostic to the choice of generative models and requires no task-specific fine-tuning.

Ackerman & Malouf present a model in which inflectional systems reduce in disorder through the action of an attraction-only dynamic.
Here we emphasise that: (1) Attraction-only models cannot evolve the structured diversity which characterises true inflectional systems, because they inevitably remove all variation; and (2) Models with both attraction and repulsion enable the emergence of systems that are strikingly reminiscent of morphomic structure such as inflection classes.
