The textbook "Postroenie massiva summ sochetaniy kalibrovannykh razmerov" offers a comprehensive analysis of the algorithmic and programming implementation for the creation and optimization of calibrated sizes. It addresses the generation of an initial array from a collection of sizes, where each size represents the sum of elements from combinations of the initial sizes. The authors, Valeriy Chepasov and Dmitriy Shipilov, explain the methodology for determining the distance between sizes to identify subsets with the maximum number of elements and specific properties. Additionally, an algorithm is presented to enhance the characteristics of the initial array by adding new sizes. This book is aimed at students and doctoral candidates in mechanical engineering programs and provides valuable insights into the optimization of technical processes.
