The book "The Quadratic Assignment Problem" by E. Cela provides a comprehensive analysis of the quadratic assignment problem (QAP), which has been regarded as a classic problem in combinatorial optimization since its introduction by Koopmans and Beckmann in 1957. The QAP is frequently used to model location problems in industry and has proven to be highly relevant in various application areas, including placement problems, scheduling, manufacturing, VLSI design, statistical data analysis, as well as parallel and distributed computing. The versatility of the QAP and the multitude of associated real-world problems make it an important topic for mathematicians, computer scientists, and practitioners. The book highlights the challenges associated with solving QAPs and offers insights into the theoretical and practical aspects of this complex issue.
