The game is described in formal terms, and its solution is found. Note that the condition of sustainable development is derived directly from the game solution. UIT\u2019s learning is analyzed. Three possible statements of the UIT\u2019s learning problem are investigated, each corresponding to a particular machine learning model. An online learning model is considered to predict the information necessary for the agent\u2019s optimal behavior in the game. A computational experiment is provided: the three learning models are applied, and the simulation results are discussed. <\/jats:p>","DOI":"10.1142\/s0219198923500020","type":"journal-article","created":{"date-parts":[[2022,8,12]],"date-time":"2022-08-12T01:49:22Z","timestamp":1660268962000},"source":"Crossref","is-referenced-by-count":1,"title":["A Model to Coordinate Interests in Investment Management"],"prefix":"10.1142","volume":"25","author":[{"given":"G.
