Number of ways to choose k items from n items without repetition and without order.
tfm.optimization.math.comb(
n, k, /
)
Evaluates to n! / (k! * (n - k)!) when k <= n and evaluates to zero when k > n.
Also called the binomial coefficient because it is equivalent to the coefficient of k-th term in polynomial expansion of the expression (1 + x)**n.
Raises TypeError if either of the arguments are not integers. Raises ValueError if either of the arguments are negative.
