The model of the cooperative problem solver based on digital twins

The model of cooperative problem solver based on digital twins is proposed. Participants of cooperation (called “dt-infs”) are considered as learnable machines for solving problems. In the processes of solving problems, such machine endowed with a finite set of states and a goal (understood as a set of solvable problems in the subject area) interacts with other members of cooperation and environmental elements through the exchange of unified messages. For each dt-inf, the subject area is represented by a task graph, designed to search for resolving structures and formalize knowledge of the tasks. The set of graph vertices is composed of task constructive objects. Each vertex has a memory represented by the task memory of the task (simple or composite) or the task area. An edge of the task graph is a pair of vertices with nonempty intersection by memory. Load of the edge is determined by the set of all pairs of memory elements included in the intersection. The proposed model is designed for use in the development of information technologies and online services.
