Abstract
We study the construction of the source-initiated (one-to-all) wireless broadcast tree to minimize the total required power for a given source node, a group of intended destination nodes and a given propagation constant, ie, the power attenuation constant /spl lambda/. The minimum energy broadcasting (MEB) problem has received much attention recently due to the two main challenges of mobile communication: the limited bandwidth of wireless networks and the limited power supply of mobile units. In a limited-bandwidth environment, push-based techniques, ie, broadcast schemes, appear to be a very effective way to allow mobile units to share the broadcast data on air. In a limited-energy environment, energy- efficient communication architectures and techniques are essential. We first give an insight analysis on the MEB problem and prove the NP-hardness of this problem. We then present an efficient heuristic called iterative maximum-branch minimization (IMBM) to approximate the construction of the minimum-energy broadcast tree, which fully utilizes the wireless broadcast advantage and demonstrates better performance compared with the related approaches. Due to the power-efficient way of the construction of the broadcast tree, the lifetime of the networks can be maximized.

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
