Q: How to view the total number of Posts and the top 100 users with the highest points in the MMA section of stackexchange

Since I am a new user of stackexchange learning community, I want to find the top 100 users with the highest points (Community Ranking) in the MMA section of stackexchange to learn their published articles, but I can't find the relevant settings or links.

@anhnha You can use GroupBy to group the curves by their values at the endpoints: (note the use of First to extract the expression from the ConditionalExpression - this makes it easier to just insert the endpoints, otherwise we would have issues since the conditions exclude the endpoints)

comb //
      BooleanConvert //(* convert to normal form *)

     Apply@List //(* convert sol1 ||
    sol2 || \[Ellipsis] to {sol1, \[Ellipsis]} *)
    Map@Apply@List (*
   convert each cond1 &&
   cond 2 && \[Ellipsis] to {cond1, \[Ellipsis]} *)//

   Map[(* for each list of conditions\[Ellipsis] *)

    ConditionalExpression[(* build a ConditionalExpression *)

      m /. ToRules[And @@ Cases[#, _Equal]] (*
      use equalities to replace parameters *),
      And @@ Cases[#, Except@_Equal](*
      extract the inequalities *)

@anhnha If you look carefully, the things that is plotted in the end is ConditionalExpression[m /. …, …] - so I am plotting m. It is simply easier to start from comb, process it, and then turn every element of the resulting list into a function to be plotted

@b3m2a1 Thank you for notifying me of this, I really need to update my old SE answer that uses ParseHTML (it doesn't exist in newer versions of jsoupLink.)
