Abstract
A structural analysis and optimization method is developed to find the optimal topology of adaptive determinate truss structures in the presence of various loading conditions. The objective function is based on the maximization of the structural strength subject to geometric constraints. The structural analysis is based on the finite element force method using the complementary strain energy and the optimization procedure is based on the Sequential Quadratic Programming (SQP) method. Equilibrium equations are satisfied a priori and compatibility conditions are derived through minimization of the complementary energy, which allows the calculation of element forces without explicitly generating the compatibility conditions. Additionally, the selection of the redundant members has been automated through the Gauss elimination technique. The proposed method has performed well and it is extremely efficient in geometry optimization of adaptive truss structures where the primary design variables are the active member forces.

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
