The deliberate function returns a jury verdict based on a simulation of deliberation
as a modified tug-of-war between two verdict factions. Can be called directly, but is
meant to be called many times to generate verdict probabilities based on g_votes and jury_n values.
Usage
deliberate(g_votes, jury_n)
Value
Returns "G" (guilty verdict) or "NG" (not guilty verdict).
Arguments
g_votes
Initial number of votes for guilty verdict (same as K value).
