FSADB.org is named for the foundation I hope to build one day. For now, it is my personal research journal as I explore Digital Biology and develop systems that can create and change their own representations.
That work began with MEGA, a working framework in which new units of representation arise during search and become available for future use. Studying how MEGA functioned, where it failed, and what kept it going led me to GADS: Generative Adaptive Dynamical Systems. GADS describes the broader architecture behind a search process that authors and regulates its own representational language.
If you’re new to the work, What Is GADS? is the shortest introduction. What kind of thing is MEGA? is a longer walkthrough of the framework from which GADS developed. It describes MEGA as it was understood in February 2026 and remains part of the research record.
GADS Foundations is the current working paper. It develops the architectural roles and the problems those roles address. The paper establishes a foundation for implementation and experiment; whether particular systems remain stable and adapt effectively must be tested.
The code is available in two repositories:
- GADS_single implements one system developing and regulating its own representations.
- GADS_network connects independent systems that exchange representations through bounded local interfaces.
I also write here as the work develops. The papers, reports, and code reflect the current state of an ongoing research program. I publish them alongside the questions, failures, and limitations that still need investigation.
The term Digital Biology is already used in bioinformatics and computational biology. My use of it is more speculative and foundational, and it is still evolving. FSADB.org is where I make that work available and record how it changes.
