MinPlusPlus< Scalar >

template<typename Scalar>
struct libsemigroups::MinPlusPlus< 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 \(x \oplus y\) which is defined by

\[ x\oplus y = \begin{cases} \min\{x, y\} & \text{if } x \neq \infty\text{ and }y \neq \infty \\ \mbox{} \infty & \text{if } x = \infty \text{ or }y = \infty; \end{cases} \]

representing addition in the min-plus semiring.

Template Parameters

Scalar

the type of the values in the semiring (must be signed integer type).

Public Member Functions
Scalar	operator() (Scalar x, Scalar y) const noexcept
	Call operator for addition.

This function returns the sum of its arguments in the min-plus semiring.

Parameters

x	the first value.
y	the second value.

Returns

The sum of x and y in the min-plus semiring.

Exceptions

This function is noexcept and is guaranteed never to throw.
