Abstract
Effort for development and maintenance of complex large software is believed to have dependency on the amount of duplicated code fragments (code clones) present in code-bases. For example, clones need to be carefully and consistently maintained and/or refactored for preventing accidental error propagation. Thus it is important to understand the proportion and evolution of clones in evolving software systems for cost estimation or the like. This paper presents a study on the evolution of near-miss clones at release level in medium to large open source software systems of different types (operating systems, database systems, editors, etc.) written in three different programming languages namely C, C#, and Java. Using a hybrid clone detector, NiCad, we detected both exact and near-miss clones at different levels of similarity. Applying statistical methods we investigated, from different dimensions, the evolution of both exact and near-miss clones, and also forecasted the amount of clones in future releases of the software systems. Our study offers significant insights into the existence and evolution of code clones and their relationships with programming language or paradigm and program size.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
