ADAPTATION SYSTEM AND ADAPTATION METHOD

Processing circuitry of an adaptation system executes a second process when a number of times of execution of a learning routine is greater than or equal to a specified number of times and less than a termination number of times. The second process performs a first trial and a second trial in each execution of the learning routine, and ends the learning routine by recording, in a storage device, a change in one of the first trial and the second trial in which a reward is larger. The processing circuitry executes a third process when the number of times of execution of the learning routine reaches a specified number of times. The third process is a process of calculating summary statistics of multiple changes and reflecting the summary statistics in a control map to complete optimization of the control map.
