Abstract: This disclosure describes techniques that facilitate the sale and exchange of plant growth systems to consumer plant growers. Particularly, a script offering system may act as an intermediary medium that allows merchants to advertise plant growth scripts to consumer plant growers via an electronic marketplace. In some examples, the script offering system may allow merchants to advertise plant growth scripts to consumer plant growers that have expressed an interest or need for a particular plant growth script. In other examples, the script offering system may allow a consumer plant grower to solicit merchant bids for the sale of plant growth script. A consumer plant grower may solicit bids for plant growth scripts that address specific needs identified via key word inputs or sensor data attributable to an existing plant growth operation that exhibits less than optimal plant growth.

Abstract: Systems and methods for training a reinforcement learning (RL) model for HVAC control are disclosed herein. Simulated experience data for the HVAC system is generated or received. The simulated experience data is used to initially train the RL model for HVAC control. The HVAC system operates within a building using the RL model and generates real experience data.

Abstract: The disclosed systems and techniques enable dual mode operation for model-based controllers in which the controllers are capable of operating in both (i) a constrained solution mode, and (ii) an unconstrained solution mode. The dual mode operation improves control because it enables the use of constrained solution mode operation when possible (constrained solution mode often enables superior control) and enables the use of unconstrained solution mode when constrained solution mode is not possible (e.g., when it is impossible to develop the constrained solution with the time available). This enables superior control when compared to typical model predictive control (MPC) controllers.
