Functions | |
double | LatticeTester::Random::randU01 () |
Returns a random number in \([0, 1)\). | |
std::int64_t | LatticeTester::Random::randInt (std::int64_t i, std::int64_t j) |
Return a random integer in \([i, j]\). | |
NTL::ZZ | LatticeTester::Random::randInt (NTL::ZZ i, NTL::ZZ j) |
This is an overload of the previous method to create an NTL::ZZ integer in the range \([i,j]\). | |
std::uint64_t | LatticeTester::Random::randBits (int64_t s) |
Returns random blocks of \(s\) bits ( \(s\)-bit integers). | |
void | LatticeTester::Random::setSeed (std::uint64_t seed=GERME) |
Sets the seed of the generator. | |
This file offers functions to generate random numbers use when making random searches.
The base generator is the 64-bit LFSR258
from [8], with period near \(2^{258}\), for 64-bit computers, and the 32-bit generator LFSR113
from [8], with period length near \(2^{113}\) on 32-bits computers. Thus the random numbers are different on 32-bits and 64-bits machines.
