Algorithmeille

Algorithmeille is a term used in theoretical computer science to describe a family of compact, self-adaptive algorithms designed to solve classes of problems with modest computational resources. The name blends 'algorithme' with a diminutive suffix to emphasize compactness and locality. In practice, an algorithmeille consists of a small core routine paired with a set of lightweight heuristics that can be activated or deactivated during execution.

Definition and operation: It runs in iterative rounds. Each round applies one or more heuristics to the current state, evaluates outcome via a simple feedback signal, and selects the next heuristic or parameter setting. The design prioritizes robustness and predictable performance across inputs rather than theoretical optimality.

Origins and usage: The term originated in informal discussions within algorithm design communities in the 2010s and 2020s as a playful label for compact, adaptive procedures. It is not an officially standardized class, and definitions vary by author.

Applications: Used for graph traversal on embedded devices, online optimization, streaming data processing, and small-scale scheduling tasks where resource constraints and responsiveness matter.

Evaluation: Performance is typically measured by empirical benchmarks, with attention to convergence time, space usage, and stability under input drift. Limitations include reduced transparency in parameter choices and weaker worst-case guarantees.
