“…Optimal control theory was born in its modern version with the Pontryagin Maximum Principle (PMP) in the late 1950's. Its development was originally inspired by problems of space dynamics, but it is now a key tool to study a large spectrum of applications extending from robotics to economics and biology [2,3,4,5,6,7,8,9,10]. Optimal control problems can be solved by two different types of approaches, geometric [2,3,5] and numerical methods [8,11,12] for dynamical systems of low and high dimension, respectively.…”
