The difference between random and pseudo-random
Oct 10, 2023 am 09:27 AM
The difference between random and pseudo-random is predictability, reproducibility, uniformity and security. Detailed introduction: 1. Predictability. Random numbers cannot be predicted. Even if the past results are known, future results cannot be accurately predicted. Pseudo-random numbers can be predicted because they are generated by algorithms. As long as you know the algorithm and seed, you can regenerate the same sequence or sequence; 2. Reproducibility, random numbers are not reproducible, and the results generated each time are independent, while pseudo-random numbers are reproducible. Yes, just use the same algorithm and seeds etc.
