In order to form and implement fundamentally new methods of education and teaching, it is necessary to use modern knowledge-intensive methods of preparing and making complex decisions, and in particular, to actively work with information presented not only in numerical and quantitative scales but also in ordinal scales such as “better–worse,” “more important–less important.” From these positions, the article uses the method proposed by the authors of the confident judgments of the decision maker (DM). It is shown that its use in selecting the most worthy applicants to continue their education in higher education will expand the powers of universities and will more accurately take into account the individual characteristics and preferences of schoolchildren and their parents; when used within the framework of an integral system for the identification and long-term development of creatively gifted students in the field of science and technology, it will make it possible to create an objective meter (creative rating) for a comprehensive assessment of the degree of creative growth of each young researcher and create based on this a scientifically managed system for supporting his guided development. As a result, a holistic system of the optimal planning of the activities of its institutes will appear in the organization of scientific activities of the university, based on target guidelines and the general development strategy of the university and at the same time taking into account the specific features of the general satisfaction with the work of the staff of each institute.</p>","PeriodicalId":50223,"journal":{"name":"Journal of Computer and Systems Sciences International","volume":"7 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142225752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimality criterion takes the form of an integral quadratic estimate of the controlled state function in the spatiotemporal domain of its definition. A parameterized representation of the control inputs is given with the required accuracy within special intervals of the optimal process, where the control inputs cannot be determined using first-order analytical optimality conditions. The proposed approach is based on the previously developed alternance method for constructing parameterized algorithms of programmed control, which heavily relies on the fundamental regularities of the subject area. It is demonstrated that the equations of the optimal regulators within the special intervals are reduced to the linear feedback algorithms based on the measured states of the objects. These algorithms are supplemented with switches at the boundary points to apply the admissible control inputs corresponding to the calculated values of the controlled variable.</p>","PeriodicalId":50223,"journal":{"name":"Journal of Computer and Systems Sciences International","volume":"6 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Estimates of the area and performance of the proposed structural models of finite-state machines are given, and recommendations for their practical use are given.
