Paper – Time manipulation technique for speeding up reinforcement learning in simulations

Today I read a published paper “Time manipulation technique for speeding up reinforcement learning in simulations”

The abstract is:

A technique for speeding up reinforcement learning algorithms by using time manipulation is proposed. It is applicable to failure-avoidance control problems running in a computer simulation. Turning the time of the simulation backwards on failure events is shown to speed up the learning by 260% and improve the state space exploration by 12% on the cart-pole balancing task, compared to the conventional Q-learning and Actor-Critic algorithms.
