RNGWR (Random Number Generator Without Repetition) is a C++ program that generates a sequence of random numbers without repetition at constant speed (O(1)) and memory consumption (O(1)). The program offers four different strategies for generating random numbers, named 'SUPER1', 'SUPER2', 'SUPER3', and 'SUPER4', which balance between computing speed and random quality using a mix of sampling and cryptographic techniques.

To use the program, you can check the main file located at ./src/main.cpp. To compile the program, simply run the 'make' command in the terminal. Once compiled, you can run the program using the command './bin/program'.

The program generates a sequence of random numbers, and each number is unique. For example, when num_samples=5 and max_values=5 the program may output "1 5 2 3 0", "0 4 3 2 5" or "1 4 0 5 2", ... depending on the random seed.

The command 'make test' generate the program './bin/test_program'. It will run unit tests, produces OPERM5 test based on chi2, uniform test based on chi2 and the computing speed (micro-seconds) for generating 10,000 numbers.
