In the previous papers[1]–[3], nonlinear continuous functions could be well simulated by nonlinear resistance. Its mathematical basis came from the applicability of the fractional power approximation. From a view of using transistor-junction characteristics, the use of exponential functions...

The stochastic-agent-on-tree method for business valuation is proposed by applying the game theory to the agent-based model. The proposed method is reduced to the real option valuation method using approximations. Demand forecasting and business valuation for computer-related industries are...
