Detailed Description

RandomBit Mutation.

Description

Change the i-th bit with a random one with mutationRate probability.
The new bit is extracted with an equal probability for zero and one.
This differ from FlipBit for at least two points:

• it requires the double of random access (extractions)
• if a mutation occur, it remains a 50% probability that bit remain the same
