Detailed Description

template<typename Int = int, class RandomGenerator = std::mt19937, class RandomDevice = std::random_device>
class cds::opt::v::random_shuffle_permutation< Int, RandomGenerator, RandomDevice >

Permutation generator based on std::shuffle.

The class is suitable for opt::permutation_generator option.

The generator produces a permutation of [0, nLen) sequence. The generator instance allocates a memory block.

Template parameters:

• Int - specifies the type of generated value, it should be any integer.
• RandomGenerator - random generator, default is std::mt19937
• RandomDevice - random device, default is std::random_device
