1. A host device comprising:
a communication interface configured to communicate with a storage device; and
a processor configured to:
generate an offspring population from a population including individual groups respectively corresponding to parameters of a model for calculating a delay time to delay writing of data to the storage device using a genetic operator,
select a preset number of individual groups among the individual groups included in the population and the offspring population based on a non-dominant rank and a cluster distance, and
control the communication interface to transmit the selected individual groups to the storage device.
