The Ali Decision Intelligence team has developed a large model-based mathematical tool called MindOpt Copilot. This tool is built on Ali's self-developed large model, solver, and modeling language. Utilizing the underlying general-purpose Qianwen large model, it transforms optimization problems described by users in natural language into optimization models of linear programming and mixed-integer linear programming, providing optimal solutions. MindOpt Copilot can be used to solve resource allocation and optimization problems in various scenarios, such as catering, retail, logistics transportation, and manufacturing.
