    Rocdocmac, we are clearly well matched: I had a misenumeration  and a miscount, and I’ll raise you my typographical error.

  20. CaptainEd's post in Coloring a grid was marked as the answer   
  21. CaptainEd's post in Balancing Gold Coins was marked as the answer   
    First, I define Restricted and Unrestricted coins, then describe and prove the algorithm for Restricted coins. Next, I request a slight tweak to the OP conditions--one additional coin known to be good. Then comes the definition of the procedure for Unconstrained coins, followed by the edge case (how many coins with only one weighing), and the formula for the Unconstrained case, since the OP requests the Unconstrained formula. 
    Then come the first few values.


  22. CaptainEd's post in The lion and the tamer, Part 2 was marked as the answer   
    I'm embarrassed to admit that I don't know enough math to develop a closed form for the distance.
    So, simulating 
    * the Tamer starting at ( 0,0 ), 
    * the Lion starting at (0,1 )
    * the Tamer moving along X-axis in increments of .01

    Suppose the point in the middle is called C . By "in the middle", do you mean "C is equidistant from the other two points"? or do you simply mean a line segment from one point to the other passes through C? I imagine different answers for the two cases.
     
    Assuming C is between A and B,
