ACCOUNTING FOR UNCERTAINTY IN THE CHOICE OF FORMULAS WHEN SOLVING PHYSICAL PROBLEMS

The problem of estimating the complexity of choosing formulas when solving educational physical tasks on a particular topic is analyzed. As a result, it is established: 1) the complexity of the solution depends on: a) the semantic complex-ity of the condition, keywords, initial and final formulas; b) the structural com-plexity of the text containing the above elements of solving the problem; c) the difficulty of finding a way to solve the problem, the uncertainty of choosing the "appropriate" formula; 2) if the tasks relates to the j-th topic of the i-th section of physics, then to account for the uncertainty of the formula choice, it is necessary to add the logarithm of the number of topics in the i-th section of physics with the logarithm of the number of formulas in the j-th topic. As an example, the assessment of the physical complexity of solving the task from the Unified State Exam is made.
