Here are some other pages I stumbled into. These aren't that great but
   have information.
   [1]https://wiki.pathmind.com/deep-reinforcement-learning <-- this is
   not a wiki, but rather a misleadingly named corporate advertisement.
   however, it appears to give a thorough description of reinforcement
   learning and its terms and math.
   [2]https://venturebeat.com/2021/10/12/deepmind-is-developing-one-algori
   thm-to-rule-them-all/ <-- this is a less-than-a-year-old article on a
   little bit of the work google is doing on cross-algorithm and
   cross-representation problem solving. I find it hard to find and engage
   such information. the concept is expected to quickly lead to much more
   powerful systems. mentions papers and researchers' names. google tends
   to open source their research into their various repositories.
