Yi Ting is an author about whom limited public information is currently available; the library holds only one work by this author, Mathematical Modeling. Judging from the title and its common classification as popular science, the book presumably centers on mathematical modeling and is intended for readers who wish to understand modeling ideas and methods. Mathematical modeling is the process of translating real-world problems into mathematical language and solving them, involving steps such as model assumptions, variable selection, solution, and verification; it is widely used in science and engineering study and in the analysis of practical problems. Yi Ting's writing in this direction serves an introductory and popularizing role, seeking to present relatively specialized content in a more readable form for general readers. Because the author's nationality, dates of birth and death, education, and personal experience cannot be confirmed, this introduction makes no speculation and offers only an objective description of the subject and positioning of the surviving work.
