1. An elevator group management device comprising:
processing circuitry configured to:
estimate a traffic flow based on boarding and alighting floors of users and a number of boarding and alighting people of an elevator,
determine a policy of running of a car based on the traffic flow estimated,
evaluate operational efficiency at a time when the car is virtually run based on the policy determined, and
display information indicating a status of learning,
the processing circuitry calculating, as an improvement state of the operational efficiency, a ratio of a difference between a pre-improvement average waiting time and a post-improvement average waiting time to the pre-improvement average waiting time.
