template<typename Scalar>
struct libsemigroups::MinPlusProd< 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 by
\[ x\otimes y =
\begin{cases}
x + y & \text{if } x \neq \infty\text{ and }y \neq \infty
\\ \mbox{}
\infty & \text{if } x = \infty \text{ or }y = \infty;
\end{cases}
\]
representing multiplication in the min-plus semiring.
- Template Parameters
-
| Scalar | the type of the values in the semiring (must be signed integer type). |
