I'm a PhD researcher at the University of Tsukuba working with evolutionary computation and Quality-Diversity algorithms. What draws me to this field is the capacity of evolution to generate a wide variety of solutions without being told what to look for — novelty and diversity as a feature, not a side effect. I build simulations and tools that explore this idea: artificial creatures, procedural generators, open-ended systems where interesting things emerge from simple rules. If you want a quick taste, I made a demo inspired by Picbreeder in PICO-8 that you can try here. You can also find my projects on GitHub and follow my writing on the blog.

Projects [top]

  • SoftbodyGodot
    -- /non4to/SoftbodyGodot
    Artificial Life simulation of softbody organisms that self-replicate, form physical attachments, and evolve behavior over time. Each organism carries a gene encoding movement, attachment, and survival strategies. Built in Godot 4 with Rapier2D.

  • RGPlants - PROCJAM2024 (2024)
    -- /non4to/PROCJAM-2024
    Open-ended evolution simulation where 4,096 color-coded organisms spread, blend, and mutate across a grid. No fitness function — only emergent patterns from local neighbor interactions. Built with Python and Pygame. Submitted to PROCJAM 2024.

  • RPG NPC file creator (2023)
    -- /non4to/CharacterFiles
    Genetic algorithm that evolves balanced TTRPG character sheets toward a user-defined win rate. Fitness evaluated via Monte Carlo simulation — 1,000 combat simulations per individual. Built with Python.
