"traverse" move proposal parameter.
"walk" move proposal parameter.
Probability determining the number of parameters that are changed.
Move probability of "traverse" moves, default to 0.4918
Move probability of "walk" moves, default to 0.4918
Move probability of "blow" moves, default to 0.0082
Move probability of "hop" moves
