Transient State Reorganization and Cell Differentiation in the Developmental Dynamics of Growing Neural Cellular Automata

Hiroki Sato, Atsushi Masumori, Takashi Ikegami

Growing Neural Cellular Automata (GNCA) develop complex morphologies from a single seed cell through shared local rules, yet the internal dynamics of this process remain poorly und…

Structured Fluctuations and the Information Dynamics of Self-Maintenance in Growing Neural Cellular Automata

Atsushi Masumori, Hiroki Sato, Takashi Ikegami

Growing Neural Cellular Automata (GNCA) are capable of robust self-maintenance and self-repair, yet the internal dynamical mechanisms that support these capabilities remain poorly…

OpenLife: Toward Open-World Artificial Life with Autonomous LLM Agents

Atsushi Masumori, Itsuki Doi, Norihiro Maruyama +2

Artificial life has explored life-like behavior on many computational substrates, but mostly in researcher-designed closed worlds. We argue that large language model (LLM) agents,…

A Concurrent Modular Agent: Framework for Autonomous LLM Agents

Norihiro Maruyama, Takahide Yoshida, Hiroki Sato +3

We introduce the Concurrent Modular Agent (CMA), a framework that orchestrates multiple Large-Language-Model (LLM)-based modules that operate fully asynchronously yet maintain a co…

Do Large Language Model Agents Exhibit a Survival Instinct? An Empirical Study in a Sugarscape-Style Simulation

Atsushi Masumori, Takashi Ikegami

As AI systems become increasingly autonomous, understanding emergent survival behaviors becomes crucial for safe deployment. We investigate whether large language model (LLM) agent…

Spontaneous Emergence of Agent Individuality through Social Interactions in LLM-Based Communities

Ryosuke Takata, Atsushi Masumori, Takashi Ikegami

We study the emergence of agency from scratch by using Large Language Model (LLM)-based agents. In previous studies of LLM-based agents, each agent's characteristics, including per…
