Before revision:  Analytically tractable results are obtained by using the fluctuation theory. These results predict not only the moment for changing strategy in a matrix form but also the prior moment of the change. This explicit model could be adapted into practically every strategic decision making situations which are described as a matrix form with the quantitative measures of the decision parameters .
