Deterministic Random Number Generation
True physical randomness is difficult to generate computationally, so systems use mathematical algorithms to produce pseudo-random numbers. These numbers appear random but are determined by an initial value called a seed.
Using a seed is highly valuable because it makes the random sequence repeatable. This is essential for testing algorithms, replicating scientific experiments, or sharing specific random results with others.
The core mapping formula is:
$$\text{Value} = \text{Min} + \text{Ratio} \times (\text{Max} - \text{Min})$$
