template<typename Scalar>
struct libsemigroups::MaxPlusProd< Scalar >
Defined in matrix.hpp.
This is a stateless struct with a single call operator of signature: Scalar operator()(Scalar x, Scalar y) const noexcept that returns \(x \otimes y\) which is defined bitset_type
\[ x\otimes y =
\begin{cases}
x + y & \text{if } x \neq -\infty\text{ and }y \neq -\infty
\\ \mbox{}
-\infty & \text{if } x = -\infty \text{ or }y = -\infty;
\end{cases}
\]
representing multiplication in the max-plus semiring.
- Template Parameters
-
| Scalar | the type of the values in the semiring (must be signed integer type). |
