Abstract: in this paper the comparative analysis was performed for two-parametric game model solver algorithm by means of a numeric example. In the first part of this paper the functional meanings of the value of the game and the probabilities of the given strategies were compared with the numerical solutions for the given points of d,t parameters. The same analysis was performed for the different numbers of discrets. The accuracy and reliability of the outcome values was analyzed. All the data shown in this paper were obtained with the help of an applied software package. The final results are given in the form of tables.
Keywords:parametric game model, differential transform, comparative analysis, parametric linear programming problem, two-parametric game model solver algorithm.
Experimental details. To check the performance and accuracy of the two-parametric game model solver algorithm [1, 2], we consider an example:
The following game model payoff matrix with d, t functional coefficients is presented below:
The parametric linear programming problem of the game will be the following:
game model solver algorithm
For solving the game we choose the following parameters: K1 = K2 =5 , H1 =H2 =1(the parameters needed to apply the method of differential transforms [4, 5]), d=10, t=10. With the help of the applied package of program [3] the following solutions are obtained:
The parametric function of the value of the game:
The functions of the probabilities of the given strategies:
Results and discussion. In order to check the accuracy of the obtained results, we perform comparative analysis between the values of the X1(d,t ) , X 2(d,t ), X3(d,t),V(d,t) functions in selected points of the d,t parameters and the numerical results of the same problem for the 10<= d <20.4 , 10<= t <=50 ranges of the given d, t parameters. As we see from table 1 the results obtained by both ways of solving the model are equivalent with the exception of the last points for d parameter, which is explained by the level of bias while determining the bounds of optimality of d,t parameters.

The values of the function V(d,t ) in some d,t points for different K1,K2 values of discrets are portrayed in table 2 as well as numerical items of the game value of non parameter game for each d,t point. The research of the experiments shows that the accuracy of the results grows while increasing the numbers of K1,K2 discrets. In particular, for the given example the most precise results are achieved in case of the K1=10,K2=10 counts of discrets.

Comparative analysis was performed between the acquired results and already known solutions. The obtained results was analyzed for the different values of K1, K2 parameters for the function of the game V(d,t ) and for the X1(d,t ) , X 2( d,t ), X3( d,t ) functions in some of the d,t points. The precision of the presented values were substantiate.
