Random vector
Webb1 apr. 2024 · The reason for removing std::random_shuffle in C++17 is that the iterator-only version usually depends on std::rand, which is now also discussed for deprecation. ( std::rand should be replaced with the classes of the header, as std::rand is considered harmful .) In addition, the iterator-only std::random_shuffle version usually … WebbRandom Vectors Definition: Let (;F;P) be a probability space.
