Here is some sample output:
...

Time is 2 the genome is 0 0 0 0 0 0 0 0 0 0
base 0 = 0
base 1 = 0
base 2 = 0
base 3 = 0
base 4 = 0
base 4 mutated to 1
base 5 = 0
base 6 = 0
base 7 = 0
base 8 = 0
base 9 = 0

*** The first kind of error appears here:
Time is 3 the genome is 0 0 0 0 0 0 0 0 0 0
*** The line above should have read:
*** Time is 3 the genome is 0 0 0 0 1 0 0 0 0 0
*** print out of genome in the main loop on pass 3 does not reflect the  
mutation on pass 2
base 0 = 0
base 1 = 0
base 2 = 0
base 3 = 0
base 4 = 1
base 5 = 0
base 6 = 0
base 6 mutated to 1
base 7 = 0
base 8 = 0
base 9 = 0

*** again here
Time is 4 the genome is 0 0 0 0 0 0 0 0 0 0
*** should be :Time is 4 the genome is 0 0 0 0 1 0 1 0 0 0
base 0 = 0
base 1 = 0
base 2 = 0
base 3 = 0
base 4 = 1
base 5 = 0
base 6 = 1
base 7 = 0
base 8 = 0
base 9 = 0

Time is 5 the genome is 0 0 0 0 0 0 0 0 0 0
base 0 = 0
base 1 = 0
base 1 mutated to 1
base 2 = 0
base 3 = 0
base 4 = 1
base 5 = 0
base 6 = 1
base 7 = 0
base 8 = 0
base 9 = 0

*** now genome is correctly updated!
Time is 6 the genome is 0 1 0 0 1 0 1 0 0 0
base 0 = 0
base 1 = 1
base 2 = 0
base 3 = 0
base 4 = 1
base 4 mutated to 1
base 5 = 0
base 6 = 1
base 7 = 0
base 8 = 0
base 9 = 0

Thank you,

Vincent
