@ -9,12 +9,17 @@ Abstract:
Poly DD package
Internal nodes are of the form x*hi + lo
Non-leaf nodes are of the form x*hi + lo
where
- maxdegree(x, lo) = 0,
Leaf nodes are of the form (0*idx + 0), where idx is an index into m_values.
- reduce(a, b) reduces a using the polynomial equality b = 0. That is, given b = lt(b) + tail(b),
the occurrences in a where lm(b) divides a monomial a_i, replace a_i in a by -tail(b)*a_i/lt(b)
- try_spoly(a, b, c) returns true if lt(a) and lt(b) have a non-trivial overlap. c is the resolvent (S polynomial).
