arXiv:2606.05408v1 Announce Type: new Abstract: When an LLM repeatedly mutates a program, does it explore new forms or circle back to the same ones? We study this question by analyzing LLM-driven mutation chains in the absence of selection pressure within a domain-specific language, varying prompt design, model family, and stochastic replication. We find that LLM-based mutation consistently converges toward restricted attractor regions in program space. Convergence is especially severe at the structural level: in 87% of chains, over 93% of mutations revisit a previously seen structural form, w
This research provides early insights into the inherent dynamics of LLMs as program mutators, a critical observation as autonomous AI agents develop rapidly.
A strategic reader should care because the findings suggest structural limitations in LLM-driven program evolution, impacting the promise of fully autonomous code generation and adaptation.
This research implies that without external selection pressure, LLMs may not explore diverse solutions, necessitating new strategies for leveraging them in evolutionary programming.

LLMs, when used for program mutation without selection, tend to converge on previously seen structural forms, limiting exploration.
This convergence necessitates the development of sophisticated selection mechanisms or human oversight to guide LLM-based program evolution towards novel and effective solutions.
The inherent limitations identified could lead to a re-evaluation of the 'singularity' path of fully autonomous AI, emphasizing integrated human-AI systems for complex problem-solving.
