move Maxwell distribution from computed vector to just a vector
Thanks to suggestion of Graham Dennis, this skip unnecessary calculations
of the Maxwell probability distributions at every step since. Thus
avoids recalculation.
Below the original comment:
Your computed_vector's "Maxwell_distribution_probabilities" and
"Maxwell_distribution_probabilities_norm" are constant. If you just
change them to be <vector> elements changing the <evaluation> tags to
<initialisation> tags, this will ensure that they are not evaluated
every time they are needed.
