Abstract
This study develops an optimization framework to determine optimal operating strategies in monoculture and polyculture hydroponic systems considering uncertainty and disturbances. A key novelty of this work is the development of a polyculture hydroponic model incorporating interspecies nutrient interactions and dynamic environmental factors into the optimization problem, offering insights for system management and sustainability. A mechanistic nutrient uptake and growth model captures system dynamics and improves resource efficiency while accounting for parameter uncertainty and external disturbances to enhance system resilience. A case study of hydroponic polyculture soybean and tomato plants demonstrates the benefits of this approach. Results show that hydroponic systems increase yield by over 60% compared to traditional farming. Compared to monoculture hydroponics, polyculture methods reduce nitrogen consumption by 40% and increase annual profit by 3.91% per kilogram of fruit. These findings highlight the importance of nitrogen supply management and demonstrate how computational optimization can advance sustainable agriculture. • Hydroponic cultivation is a form of agricultural process intensification. • Polyculture systems offer interspecies benefits compared to monoculture systems. • Optimization framework determines optimal operating strategies under uncertainty. • Mechanistic nutrient uptake and growth models are used to capture system dynamics. • Case study of polyculture hydroponic system demonstrates improved sustainability.

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
