Based on PARL, the A2C algorithm of deep reinforcement learning has been reproduced, reaching the same level of indicators as the paper in Atari benchmarks.
A2C is a synchronous, deterministic variant of Asynchronous Advantage Actor Critic (A3C). Instead of updating asynchronously in A3C or GA3C, A2C uses a synchronous approach that waits for each actor to finish its sampling before performing an update. Since loss definition of these A3C variants are identical, we use a common a3c algotrithm parl.algorithms.A3C
for A2C and GA3C examples.
Please see here to know more about Atari games.
