Weighter

A type alias for a function that computes the weight of an object for weighted random selection.

The Weighter is a function that takes an element of type E and returns a Double representing its weight. It is used in cases where elements do not implement Weighted directly, allowing custom weight computation.

Example

data class Item(val name: String, val importance: Double)

val items = listOf(
    Item("Basic", 1.0),
    Item("Advanced", 2.0),
    Item("Premium", 5.0)
)

val selector = RandomSelector.fromWeightedIterable(items) { it.importance }

println(selector.pick()) // Outputs an item based on its importance
