Abstract
This paper presents the approach of using an evolutionary algorithm with adaptive search space (EAASS) in identifying the hysteresis parameters of an electromechanical valve actuator. The proposed EAASS features an adaptive mechanism to control the search space as well as the rate of crossover. According to the normalized fitness distance in each generation, EAASS consistently identifies the best search domains in the parameter space and adjusts the crossover rate in order to improve the solution accuracy. To further enhance the robustness, EAASS allows the crossover rate to grow exponentially and the mutation rate to decay logarithmically according to the generation number. The hysteresis model of a simulated valve actuator identified by EAASS has shown high accuracy.

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
