| contents | Achieving optimality in controlling physical systems is a profound challenge across diverse scientific and engineering fields, spanning neuromechanics, biochemistry, autonomous systems, economics, and beyond. Traditional solutions, relying on time-consuming offline iterative algorithms, often yield limited insights into fundamental natural processes. In this work, we introduce a novel, causally deterministic approach, presenting the closed-form optimal tracking controller (OTC) that inherently solves pseudoconvex optimization problems in various fields. Through rigorous analysis and comprehensive numerical examples, we demonstrate OTC's capability of achieving both high accuracy and rapid response, even when facing high-dimensional and high-dynamical real-world problems. Notably, our OTC outperforms state-of-the-art methods by, e.g., solving a 1304-dimensional neuromechanics problem 1311 times faster or with 113 times higher accuracy. Most importantly, OTC embodies a causally deterministic system interpretation of optimality principles, providing a new and fundamental perspective of optimization in natural and artificial processes. We anticipate our work to be an important step towards establishing a general causally deterministic optimization theory for a broader spectrum of system and problem classes, promising advances in understanding optimality principles in complex systems. |
