The technology of the present invention relates to an information processing device and information processing method that make it possible to realize various variations of various event scenes in a simulator environment that simulates the real world. A reward provision unit provides rewards to a first agent and a second agent that act in a simulator environment which simulates the real world and that learn action determination rules in accordance with rewards in respect to the act. A reward in accordance with a prescribed reward definition is provided to the first agent. In addition, a reward in accordance with an opposing reward definition is provided to the second agent, the opposing reward definition being in opposition to the prescribed reward definition such that the obtained reward becomes larger when the second agent acts to create a situation in which the reward of the first agent becomes smaller, and the obtained reward becomes smaller when the second agent acts such that the reward of the first agent becomes larger. The technology can be applied to reinforcement learning for an agent, for example.
