Excellent undergraduate and master's graduates from the Department of Mathematical Sciences of Tsinghua University, PhD from the w88 casino of Creative Media, City University of Hong Kong, and worked in "Soft Computing》、《Information Sciences》、《Applied Mathematics and Computation》and other academic journals and academic conferences20Multiple papers,Winner of the Sixth Higher Education Institutions Scientific Research Outstanding Achievement Award of the Ministry of Education, project leader of the National Natural Science Foundation, leader of the first academic innovation team of the w88 casino, overseas review expert of the Hong Kong Research Grants Council,IEEE Transactions on Fuzzy SystemsReviewer for other international journals. He is from the w88 casino of Information, w88 casino80Post-teacher Ni Yaodong.

This year, Ni Yaodong published the paper "Minimizing the Expected Complete Influence Time of a Social Network》won the third prize in management in the 6th Higher Education Institutions Scientific Research Outstanding Achievements Award of the Ministry of Education. This articleOnAs an important achievement in the social network influence diffusion theory, this article studies the diffusion mechanism and diffusion optimization problem of dominant influence in social networks, innovatively proposes an incremental opportunity model, and gives the mathematical properties of the incremental opportunity model. Ni Yaodong proposed the social network expectation completely affected time minimization problem, established a decision-making model for this problem, designed a heuristic algorithm framework based on greedy algorithm, and implemented a series of experiments to verify the effectiveness and stability of the algorithm.

The issue of social network influence diffusion has been a hot international issue in recent years. This paper by Ni Yaodong is from2010Published in yearSince,Attracted many scholars from sociology, economics, management, information science, infectious diseases and other fields.Not onlySSCI、SCIIncluded in the database and wasSSCIandSCICitations of included journal articles5times,Provide theoretical support and decision-making methods for practical issues such as Internet marketing (such as strategy formulation and optimization of emerging marketing models such as viral marketing), information security (such as network information confidentiality and effective filtering), medicine and health (such as prediction and prevention of infectious diseases).

From mathematics to creative media majors, Ni Yaodong’s scientific research interests have always centered around computer technology, especially the application of artificial intelligence technology in economics and management science, including social network management, e-commerce based on agent technology, game theory, intelligent computing, etc. at Tsinghua University6years of study in mathematics gave him solid professional knowledge. And at City University of Hong Kong3years of studying for a PhD in creative media gave him a taste of the wonders of interdisciplinary research.“Stones from other mountains can attack jade.”Ni Yaodong said that if you study a subject field for too long, you will often be instilled with too many previous opinions and form inertial thinking. One of the advantages of interdisciplinary studies is to use the thinking and knowledge of the disciplines studied to observe the results of other disciplines, discover new professional highlights, and find new breakthroughs.

When talking about this award-winning experience, Ni Yaodong said frankly that essay writing requires necessity and contingency. Since his undergraduate studies, Ni Yaodong has developed the habit of reading literature late at night. Getting rid of the complicated daily routine work, the quiet night allows him to better absorb knowledge and thinking, and even bring unexpected inspiration. This award-winning paper was a topic that suddenly came to his mind when he was reading literature alone late at night. Solid professional knowledge and extensive literature reading are inevitable conditions for producing scientific research results. The use of breakthroughs in interdisciplinary subjects is the chance to produce an excellent paper, providing creativity for scientific research work.

The experience of studying abroad in Hong Kong not only gave Ni Yaodong inspiration in interdisciplinary subjects, but also gave him a new understanding of scientific research. “If you want scientific research results to have the greatest impact, you must write in English and go international.”The papers published by Ni Yaodong are basically written in English, and the journal papers are basically published in international journals. The internationalization strategy of the University of Economics and Business should not only be reflected in talent training, but also in teaching and scientific research. Ni Yaodong requires the master students he supervises to be like himself, encouraging them to submit papers to international journals during their studies, so that they can adapt to this international scientific research method during their studies and more quickly integrate with international standards.

Ni Yaodong’s teaching work is as outstanding as his scientific research work. He undertakes three to four teaching courses each semester. The master’s thesis he supervised won the w88 casino’ Outstanding Master’s Thesis. He himself also won the third prize in the w88 casino’s third young teacher teaching basic skills competition. “Pressure is motivation. "On the road of teaching and scientific research, Ni Yaodong is moving forward firmly and resolutely.
