Abstract: The trajectory of solutions is calculated by numerically integrating deterministic differential equations, and when sampling along this trajectory, it is set in such a way that a distribution obtained by combining a plurality of Tsallis distributions in which the solution of differential equations covers an energy range wider than that of a Boltzmann-Gibbs (BG) distribution can be reproduced. Several values are set to the parameter of the Tsallis distribution, and a distribution is obtained by combining Tsallis distributions each corresponding to a different parameter value. Using sampling points sampled from the trajectory obtained from the distribution obtained by combining a plurality of Tsallis distributions, the physical and chemical characteristics of a physical system according to the BG distribution can be calculated by a method of statistical mechanics.
