In 1953, under the guidance of Alexey Andreevich Lyapunov, Yuriy Ivanovich completed his first serious scientific work on minimizing partially defined Boolean functions.

After defending his thesis in 1957, he entered graduate school at Moscow State University, where he worked with A.A. Lyapunov in the department led by Academician Sergey Lvovich Sobolev.

Working on a practical problem of testing a wide class of technical devices, Zhuravlev developed a special mathematical approach that later inspired numerous studies by both Soviet and international scientists.

This theory formed the basis of his Doctor of Science dissertation, which Zhuravlev defended in 1965 in one of the first defenses in the field of “Mathematical Cybernetics.” His opponents included cybernetics experts Academician V.M.

Yuriy Ivanovich introduced and researched the now-classic model of estimation computation algorithms (ECA), unifying most of the known recognition principles and procedures at that time.

Today, ECA is a highly versatile language for describing recognition procedures, widely applied to solve practical tasks and inspiring new theoretical research.

Under Yuriy Ivanovich’s guidance, students and colleagues have solved numerous applied problems in fields such as medicine, geology, social and economic forecasting, creating software systems for decision support, recognition, classification, and prediction.

From 1976 to 1978, Zhuravlev published a series of papers on the now-famous algebraic approach to the synthesis of correct algorithms, establishing the modern framework for recognition and many related fields of applied mathematics and computer science.

These works, like his earlier studies on ECA, inspired a continuing stream of research that solidified Zhuravlev’s school’s global leadership in mathematical recognition methods.

Since 1989, he has been a member of the Executive Committee of the International Association for Pattern Recognition (IAPR); since 1990, a member of the Bureau of the Department of Informatics, Computer Engineering, and Automation of the RAN; and since 1991, Editor-in-Chief of the international journal “Pattern Recognition and Image Analysis.” In 1997, he founded and headed the Department of Mathematical Forecasting Methods at the Faculty of Computational Mathematics and Cybernetics of Moscow State University.

Since his presentation at the IFIP World Congress in New York in 1965, Yuriy Ivanovich has regularly given lectures abroad, including courses in universities in the USA, France, Finland, Sweden, Austria, Poland, Bulgaria, East Germany, and others.
