1. An operation quantity determination device for determining an operation quantity related to a molding machine, the device comprising:
a processor; and
a storage storing instructions for causing the processor to execute processes of:
acquiring observation data obtained by observing a physical quantity related to molding by the molding machine;
generating a state expression map expressing a state of the molding machine based on the acquired observation data; and
outputting the operation quantity based on the generated state expression map,
wherein the state expression map is a model that outputs a reward for setting the operation quantity in a state and a state transition probability to a next state when an initial information and the observation data and an operation quantity are input.
