A predetermined number of times that a simulator can be used for learning is set. Every time the simulator is used, a count indicating the number of times that the simulator is already used is incremented. When the count is lower than or equal to the predetermined number of times, a simulation condition for use in a simulation is randomly set, and, when the count exceeds the predetermined number of times, a fixed simulation condition continues to be used in subsequent sessions of the simulation. |
