WhatsUp on 2022-09-28 18:10: I looked at the first part (first 10 letters) which breaks down to the following task. Enter 10 letters a0..a9 and calculate b0 = 0.5 * a0 + 0.111 b1 = 0.5 * a1 + 0.111 b2 = 0.5 * a2 b3 = 0.5 * a3 b4 = 0.5 * a4 b5 = 0.5 * a5 b6 = 0.5 * a6 b7 = 0.5 * a7 + 0.128 b8 = 0.5 * a8 + 0.111 b9 = 0.5 * a9 X = b1 * b6 + b0 * b5 + b2 * b7 + b3 * b8 + b4 * b9 Y = b1 * b1 * b6 + b0 * b0 * b5 + b2 * b2 * b7 + b3 * b3 * b8 + b4 * b4 * b9 The aim is to get X - Y * Y == -463428064699.207458 I don't know how to solve this in a clever way. It seems that the solution is probably not unique, by exchanging b0, b1 and b5, b6. The second part deals with the remaining letters, but is of the same flavor, adding some log functions at some point.
