Abstract
This study proposes a Semi-centralized Multi-agent Reinforcement Learning (SC-MARL) approach for irrigation scheduling in agricultural fields, which are characterized by spatial variability and therefore delineated into management zones. The SCMARL framework is hierarchical in nature, with a coordinator agent at the top level and local agents at the second/lower level. The coordinator agent makes daily ‘yes/no’ irrigation decisions based on field-wide observations from all the management zones, which are then communicated to local agents. These local agents are tasked with determining the optimal daily irrigation depths for specific management zones, utilizing both the coordinator agent’s decision and local observations. A comparison between the SCMARL method and a Fully Decentralized Multi-agent Reinforcement Learning approach is presented, highlighting the superior performance of the SCMARL approach in terms of water savings and improved irrigation water-use efficiency.

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
