Random

Defined in ranges.hpp.

This struct can be used to select a single random item from an input range. This can be extremely inefficient if the input range is large, because every item in the range prior to the randomly chosen one must be iterated through when get is called.

Example

auto wg = make<WordGraph<uint8_t>>(4, [[0, 1], [1, 0], [2, 2]]);
Paths p(wg);
p.source(0).max(10);
p.count();            // returns 1023
(p | Random()).get(); // returns random path in p
