This title examines the structure of approximate solutions of optimal
control problems considered on subintervals of a real line. Specifically
at the properties of approximate solutions which are independent of the
length of the interval. The results illustrated in this book look into
the so-called turnpike property of optimal control problems. The author
generalizes the results of the turnpike property by considering a class
of optimal control problems which is identified with the corresponding
complete metric space of objective functions. This establishes the
turnpike property for any element in a set that is in a countable
intersection which is open everywhere dense sets in the space of
integrands; meaning that the turnpike property holds for most optimal
control problems. Mathematicians working in optimal control and the
calculus of variations and graduate students will find this book useful
and valuable due to its presentation of solutions to a number of
difficult problems in optimal control and presentation of new
approaches, techniques and methods.
