But there were a fair number looking at SARSA and QLearning (probably because they are the most famous, fair enough).\n\n---\n![test caption](https://www.filepicker.io/api/file/EEYou1T1SKLZB6Zq2JcX)\n*This plot is views per video. I removed the even higher video from the first three weeks. \nThe first bar is \"Dynamic Programming 1\" with 76 views. (as of June 11, 2021 5:27pm ET)*\n\n---\n\nI was planning to record a new video (that isn't on youtube yet) on the following during the live session on Monday:\n- **Expected SARSA and Double Q-Learning** - these are just modifications of those important algorithms, that have their own benefits. So there will be time to review the essentials of SARSA/QL here at the same time. If there are few people attending or no other discussion here, I will do that.\n\n*But...* if lots of people show up, we could also:\n- go over something else from earlier in the course they didn't quite understand\n- or something that they didn't get a chance to watch yet\n\nSo let me know here what topic you would want to go over, or redo live: \n- Maybe it's all the essentials from TD1 and TD2 that you really need for SARSA and QLearning.\n- Or maybe it's essentials from some of these earlier topics that people seemed to have skipped like Dynamic Programming, or Mont-Carlo methods.\n\nI'll check this post on Sunday/Monday and see which option it will be.\n"
