The spinning up guide suggests iterating models in &amp;lt;5 min, so that&amp;#x27;s 7200 iterations.&lt;p&gt;&amp;gt; start with vanilla policy gradient (also called REINFORCE), DQN, A2C (the synchronous version of A3C), PPO (the variant with the clipped objective), and DDPG, ... VPG...&lt;p&gt;that&amp;#x27;s 6 algorithms, combined with a half a dozen tasks to try, whittles it down to a few hundred iterations per task&amp;#x2F;algo combo.&lt;p&gt;that, combined with a lot of paper-reading, and perhaps clever blogging is probably enough to get started.&lt;p&gt;Still, it seems beneficial to democratize DL by making these 5 minute iterations free, doesn&amp;#x27;t it?</text><parent_chain></parent_chain></comment><story><title>Key Papers in Deep Reinforcement Learning</title><url>https://spinningup.openai.com/en/latest/spinningup/keypapers.html</url></story>
