A suction flow path of a screw compressor includes a male-side flow path that opens in an axial direction with respect to working chambers in a suction process on the male rotor side and extends from a starting end positioned on one side of a virtual plane to a first termination end positioned on the other side; and a female-side flow path on the female rotor side that extends from the starting end to a second termination end positioned on the other side of the virtual plane. The male-side or the female-side first flow path wall is configured such that at least a partial area in a range from the starting end to the first or the second termination end is closer to a male-side or female-side rotor lobe section from the starting end side toward the first or second termination end side.

A hyperparameter configuration device includes at least one memory, and at least one processor configured to acquire a program execution instruction including parameter description data, the program execution instruction being written through a command-line interface, set a value of a hyperparameter of a program to be trialed, based on the parameter description data, acquire a result of a trial of the program, the trial of the program being executed with the value of the hyperparameter, and set a next value of the hyperparameter of the program, based on the result of the trial.
