Detailed Description

BIBasis::PointerLessComparator / PointerMoreComparator — pointer-deref comparators for STL containers.

Note

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

Two tiny templated function objects so a std::sort or std::set over Polynom* / Triple* collections orders by the pointed-to value rather than the raw pointer address. PointerLessComparator forwards to T::operator<; PointerMoreComparator forwards to T::operator> for descending sorts. Both throw a descriptive std::string on a null pointer so the algorithm fails loudly rather than dereferencing junk.

Currently only BooleanInvolutiveBasis::ReduceSet uses PointerMoreComparator to sort the working GBasis list descending by leading monomial before incremental reduction; PointerLessComparator is provided symmetrically for future callers.
