Detailed Description

Heuristic-weight evaluator for gbvectors, used during Groebner basis computation to drive the S-pair sugar strategy.

Note

AI-generated documentation. Verify against the source before relying on it.

Caches a per-variable weight vector (wts_), an optional flag use_component_degrees_ that mixes in the target free module's component degrees, and a Fdegs_ table of per-component degree shifts pulled from F_. The weight of a gbvector is then the wts_-weighted sum of the leading monomial's exponents plus Fdegs_[component], computed without allocating a temporary exponent vector longer than exp_size.
