About this paper
Dakota Fisher, Matthew A. Hammer, William Byrd, Matthew Might
Researchers from the University of Colorado Boulder and the University of Utah developed miniAdapton, a minimal Scheme implementation of incremental computation that successfully reconciles memoization with mutable state. The system ensures computations are efficiently re-evaluated only when their dependencies change, providing a transparent and accessible framework for understanding dynamic self-adjusting computation.
Key insights
- A highly minimal, self-contained core (under 50 lines of code) can effectively capture the essential mechanisms of dynamic incremental computation.
- Layering automated dependency management and user-friendly macros on top of a minimal core significantly improves developer experience without compromising the clarity of the underlying principles.
- Treating mutable entities as 'adapton variables' that hold expressions provides a more intuitive and declarative approach to handling dynamic dependencies and change propagation in incremental systems.
