What are the best practices for ensuring randomness in algorithms?

To ensure randomness, use a good random number generator, avoid predictable seeds, and test for uniform distribution.

Can you explain what a good random number generator is?

A good random number generator should produce numbers that are uniformly distributed and unpredictable. Examples include Mersenne Twister and cryptographic generators.

How do I test if my random numbers are uniformly distributed?

You can use statistical tests like the Chi-squared test or Kolmogorov-Smirnov test to check for uniform distribution.

What are some common pitfalls to avoid when generating random numbers?

Common pitfalls include using a poor seed, relying on outdated algorithms, and not considering the context of randomness needed.
