The evaluation process of the game diculty level is divided into three steps:
1) input generation, 2) neural network forwarding, and 3) neural network back
propagation.
In the first step, we compute the four initial values which are tax rate, mainte-
nance fee, celebration fee, and human resource fee. Then, we generate the inputs
with the following rules:
1. If the tax is larger than T tax , it has a chance to occur the economic recession
event. The player should pay an amount of money P eco as penalty if the
economic recession event occurs.
2. There is a chance that a messy event would occur if the assigned maintenance
fee is less than T maintain . The player should pay P messy as penalty if the
messy event occurs.
