Given a partition λ with n parts, the Schur polynomial is defined to be the polynomial
sλ:=∑x1m1…xnmn
where the sum is taken over all semistandard tableaux T of shape λ and mi is the weight of i in T.
There are two different algorithms for the computation of a Schur polynomial implemented which are automatically selected depending on the size of the input.
For small integers or if n≥10, the combinatorial algorithm is used. This algorithm directly applies the above definition.
