This paper summarizes the list of our works that contain researches about optimality principles for "n-person prisoner's dilemma" game. The classic model is considered through new payoff function each player allows to consider it without restrictions number players. characteristic gives an opportunity introduce time-consistent subset core dynamic In accordance with this type game we some specif...

In this paper we are concerned with the existence of optimal stationary policies for in nite horizon risk sensitive Markov control processes with denumerable state space, unbounded cost function, and long run average cost. Introducing a discounted cost dynamic game, we prove that its value function satis es an Isaacs equation, and its relationship with the risk sensitive control problem is stud...

This article discusses automatic strategy acquisition for the game \Othello" based on reinforcement learning. In our approach, two computer players initially know only the game rules, but they become relatively stronger after playing several thousands of games against each other. In each game, the players re ne the evaluation function for the game state, which is achieved in a reinforcement lea...

In this paper we are concerned with the existence of optimal stationary policies for innnite horizon risk sensitive Markov control processes with denu-merable state space, unbounded cost function, and long run average cost. Introducing a discounted cost dynamic game, we prove that its value function satisses an Isaacs equation, and its relationship with the risk sensitive control problem is stu...

This paper investigates the optimal mean-variance reinsurance-investment problem for an insurer with a common shock dependence under two kinds of popular premium principles: variance principle and expected value principle. We formulate optimization within game theoretic framework derive closed-form expressions equilibrium strategy function different principles by solving extended Hamilton-Jacob...

the aim of the present study was to investigate and compare the effects of twokinds of motivational and instructional self–talk on the performance of static anddynamic balance tasks in the elderly. for this purpose, 45 old subjects agedbetween 60 and 70 from qom province participated in this study. static balancetask (stand on one leg) and dynamic balance task (sebt test) were instructed withno...

Introduction: Respiratory and blood pressure changes as well as fluid administration alter the acid-base balance during the perioperative period which may cause consciousness disturbance and additional hemodynamic disorders. The aim of this study was to identify frequent postoperative acid-base disturbances in order to control postoperative complications. Materials and Methods: This prospective...

We formulate the dynamic of the platform size from aggregation of the best response dynamic of agents who have different exogenous cost to participate the platform, e.g. transportation costs. Then, concavity in the dynamic is no more thought as standard, because it means just concavity of the cumulative distribution function of the heterogeneous costs. We argue that non-concave (convex) one fit...
