Abstract
<div class="section abstract"><div class="htmlview paragraph">This paper describes the element interpolation scheme for multi-material topology optimization (MMTO), which generalizes the existing standard MMTO approach to overcome the inherent limitations of using only isotropic materials with a constant Poisson’s ratio. To address this limitation, the proposed method transforms the MMTO solution in a series of single material topology optimization (SMTO) by stacking multiple elements within the same design cell and assigning each weighted candidate material to an element. Solid Isotropic Material with Penalization (SIMP) equations are defined as weighting factors applied on each candidate material. As a result, anisotropic or isotropic materials with different Poisson’s ratios can be implemented in MMTO, allowing engineers to determine optimized designs that explore the full potential of isotropic and anisotropic materials properties. A thorough discussion of the element interpolation method as well the sensitivity equations are presented in this paper along with two application examples demonstrating its implementation.</div></div>

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
