Abstract
Two effective and accurate matrix collocation techniques based on novel generalized shifted Chebyshev functions of the third kind (GSCFTK) are presented to examine the approximate solutions of a fractional-order population model considering the impact of carrying capacity. The fractional operator in the Liouville-Caputo sense is considered. The first direct technique is called the GSCFTK matrix procedure whereas the second one relied on the quasilinearization method and the GSCFTK matrix collocation strategy is called QLM-GSCFTK. In both approaches, the nonlinear population model is transformed into an algebraic system of equations. The resulting matrix equation is nonlinear in the first approach while is linear in the latter one, which is more efficient than the direct matrix method. The convergence analysis of the new generalized bases is established. To testify the robustness and effectiveness of the presented techniques, various numerical simulations are performed using diverse fractional orders. The results prove the applicability of the presented techniques of providing accurate results in comparison to other available numerical models and can be extended to other similar biological problems. Results also show that the numerical schemes are robust.

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
