A second integer solution:d=2;h=1; A 4 X 4 vector Markov of a game matrix MA and an anti- game matrix MB such that game_valueMa+game_ValueMB =0 and the score is the sum of the vector out put of the Markov: MA={{0,1},{1,d}}; MB={{1/h,0},(2 - d + 1/h + h),h}}; Characteristic Polynomial is: -1 + 4 x^2 - 4 x^3 + x^4. |

COMMENT
|
Using the general game value function: gv[M_] = Det[M]/Sum[Sum[M[[i, j]]*(-1)^(i + j), {i, 1, 2}], {j, 1, 2}] and matrices: MA = {{a, b}, {c, d}}; MB = {{e, f}, {g, h}}; The solution of: Solve[{b == 1, f == 0, a == 0, Det[MA] + 1 == 0, Det[MB] - 1 == 0, gv[MA] + gv[MB] == 0}, {c, d, e, g, h}] Gives the two Matrix solution: MA={{0,1},{1,d}}; MB={{1/h,0},{2-d+1/h+h,h}}; Besides the Fibonacci:d=1and h=1 the only other obvious integer solution is: d=2 and h=1.
