“…The goal of game theory is to allow players to predict game outcomes using interactive models in which the actions and decisions of one player depend on the actions and decisions of another player, as well as their rational or irrational behavior [6,7]. Rational behavior means that the decision-making behavior of each individual would be consistent with maximizing subjective expected utility when the decisions of other individuals were known.…”

Game theory, applied in various fields, including in law, studies conflict game models and searches for their formatted solutions, makes it possible to solve many tasks and problems, predict the behaviour of subjects in various situations, thereby explaining the behavior logic of the individuals in conflict of interests. However, human behavior is not always rational (reasonable), moreover, it can be difficult to predict which strategy the player will choose when making his move in the game. In this regard, it is advisable to consider rational behavior as an accepted and reasonable behavior of game participants and irrational behavior as deviant, unpredictable behavior of players, which relies on the internal regulation of a person (beliefs, intuition, creativity, feelings, emotions, etc.) and which studies one of the developing directions of game theory in modern science – evolutionary game theory. The study aims to determine the types of irrational behavior of players, which puts other players in a difficult position and precludes from determining each other’s optimal strategies for mutual benefit and stability, using the example of legal incidents modeling through games with imperfect rationality. The authors believe, that to achieve this goal using the methods of analysis and modeling, the imperfections of rationality can be considered and studied, the types of irrational behavior of players can be defined using the games with imperfect calculation of the game, imperfect information and changes in goals during the game (with a multipersonal representation of the game) and a complete absence of rationality.

In this paper, the motion of a circular particle in a lid-driven square cavity with the power-law fluids is studied by the diffuse interface lattice Boltzmann method, and the effects of the initial position of particle, power-law index, Reynolds number and particle size are mainly considered. The numerical results show that the circular particle is first in a centrifugal motion under the effect of inertia, but finally, it moves steadily on the limit cycle. Furthermore, it is also found that the initial position of the particle has no influence on the limit cycle.For shear-thinning fluid flows, the limit cycle moves towards the bottom right corner of the square cavity. Moreover, the particle velocity is small, and the period of the particle motion is long. On the other hand, for shear-thickening fluid flows, the limit cycle moves towards the top left corner of the cavity. In addition, the particle velocity is large, and the period of the particle motion is short.With the increase of Reynolds number, the limit cycle moves towards the bottom right corner of the square cavity, which is caused by a strong fluid flow field. Meanwhile, the particle velocity becomes larger, and the period of the particle motion is shorter. With the increase of particle size, the effect of confinement of the cavity boundary becomes significant, and the circular particle is pushed toward the center of the cavity. In this case the limit cycle shrinks toward the center of the cavity. The circular particle squeezes the secondary vortices, especially when the circular particle is located in the left bottom, right bottom and left upper corners. Additionally, The appearance of the circular particle has a significant influence on the position of the primary vortex, which changes periodically around the position of the primary vortex without the particle. It is also found that the effect of the circular particle is more significant with the increase of the particle size and the decrease of the power-law index.
