"Optimization" is a fundamental lecture series in applied mathematics. It focuses on the precise and rapid calculation of the best decision when a large number of options are available. This book presents a collection of 200 exercises and exam questions with complete mathematical solutions, compiled over many years of teaching. It is a comprehensive collection that covers undergraduate knowledge. It serves as practice material for students and as a source of inspiration and selection for task setters. The problems are directly aligned with the teaching level—no skipping of difficulties—and are designed to allow for success monitoring for the students. A CD will be included with the book, containing problems with large datasets and more extensive solutions.
