  MutateCombo v2.1 Script finds mutable segments and try to find best scoring alternatives. For slow filter puzzles.

Mutate Combo v2 by rav3n_pl

2 ways of mutate:
random:
- randomly choose sphere around mutable segment and mutate in random CI
brute force:
- check all possible aas for every mutable sgmnt

]]--

-- script options there VVVVVVVV

normal=true --set false for exploration puzzles if want to explore
autoLooops=3
bruteLoops=10 --maximum brute force loops, it breaks if no change on full loop
--auto loops are first, then brute. put 0 in proper place if want only auto or brute
mutateSphere={4,7} --how big sphere around segment should be mutated: random{min,max}
shakeoutSphere=5 --how much further shake after mutate

worst=true --start mutating from worst scoring segment. if false it randomize order

chains={"G";"A";"V";"C";"P";"T";"S";"I";"L";"N";"D";"M";"H";"Q";"E";"F";"K";"Y";"R";"W"}--all of them
--chains={"G";"A";"V";"C";"P";"T";"S";"I";"L";"N";"M";"Q";"F";"Y";"W"} --desired for TNT: no ASP, GLU, ARG, LYS, HIS

maxCI=1 --maximum Clash Importance, safe from 0.1 to 1.0, under 0.1 universe might implode!
CapCI=false --when false= always use maxci as multiplier, true=just cap it to maxci when higher

filters=true --if true filters are enabled only for scoring

Added:

• slow filters can be disabled to speed up work (default in this)
• maximum CI to work witch (set to 1.0 in this version)

Options at front of puzzle.
