Nova Drop Pseudo-Random Number Generator

Overview

nova_drop is a lightweight, easy-to-use pseudo-random number generator (PRNG) designed for applications requiring random number generation with a good balance between simplicity, efficiency, and randomness quality. It features an increased state size and complex state interactions to enhance the randomness of its output.

Features

• Increased state size for longer periods and improved randomness.
• Complex bitwise operations ensure thorough mixing of state.
• Easy to integrate into any C or C++ project.
• Designed with simplicity and performance in mind.

Getting Started

Prerequisites

• A C compiler (e.g., GCC, Clang)
• Basic knowledge of C programming

Compilation

1. Save nova_drop.c and nova_drop.h in your project directory.
2. Include nova_drop.h in your source file: #include "nova_drop.h".
3. Compile your project. For example, if using GCC and your source file is main.c:

gcc -o my_program main.c nova_drop.c

Usage

Initialize the PRNG State: Before generating random numbers, initialize the state with a seed.

uint32_t state[NOVA_DROP_STATE_SIZE];
uint32_t seed = 123456789; // Example seed
nova_init(state, seed);

Generate Random Numbers: Use nova_drop to generate random numbers as needed.

uint32_t random_number = nova_drop(state);

Documentation

Functions

void nova_init(uint32_t *state, uint32_t seed): Initializes the PRNG state with a given seed. uint32_t nova_drop(uint32_t *state): Generates a pseudo-random number based on the current state and updates the state.

Constants

NOVA_DROP_STATE_SIZE: The size of the state array required by nova_drop. Currently set to 5.
