Abstract

fetched live from OpenAlex

Pros and cons of competitive analysis have been debated since its inception in mid 1980s. Much of this discussion centered around the accuracy of performance evaluation methods for paging, which is probably the most central among online optimization problems studied in the literature, and, at the same time, ironically, the most prominent example of shortcomings of competitive analysis. In this quarter's column, Reza Dorrigiv and Alejandro Lopez-Ortiz review the history of the problem, discuss several performance models from the literature, and propose a new model that avoids shortcomings of previous approaches. If you are interested in contributing to the column as a guest writer, feel free to contact me by email. All kinds of contributions related to online algorithms and competitive analysis are of interest: technical articles, surveys, conference reports, opinion pieces, and other.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
