• Description:

  This recipe: ; 1. Reduces importance of H-Bonds, alters wiggle strength and cycles W/S to get better fit to the cloud, then ; 2. Normalises H-Bond importance and cycles W/S to improve score.

  Use your normal polishing tricks after that.

  *Do not* re-run the script once you have made further improvements, like indealise or rebuild. It will only make it worse. This is just to give a good starting position while you get a coffee.

  v0.2 ; * Altered the default dialogue values for improvement-check to account for differently sized puzzles. Puzzle https://fold.it/puzzles/2013609 (~200 segments) ran in about 45 minutes on my ancient i5 and left me about mid-field 29,589 points before other work. ; * Better commenting in code. ; * Cosmetic fixes.

  v0.3 ; * Included option to either shake or wiggle first. Some people feel strongly about this - do your own research :-)

It has been pointed out to me that this recipie improperly uses the wiggle strength function. There is a new version in the works.

[AlkiP0Ps]

Do not use this version, as wiggle power is borked. Seek a later version, Bruno K's or something else.
