generate_random_weighted

Select random options based on weighted probabilities for use in lotteries, item drops, task assignments, or A/B testing using EVM block hash for secure randomization.

Instructions

Weighted Random Selector

Randomly select an option based on weights

Args:
    options (List[str]): List of options
    weights (List[int]): Corresponding weight list (0-1000)
    salt (str, optional): Random number salt value. Defaults to "".

Returns:
    str: JSON string containing the selection result

Application Scenarios:
1. Lottery systems (prizes with different probabilities)
2. Random drops (weighted item drops)
3. Task assignment (based on priority)
4. A/B testing (experiment groups with different ratios)
