[−][src]Trait ddo::abstraction::heuristics::NodeSelectionHeuristic

pub trait NodeSelectionHeuristic<T> {
    fn compare(
        &self, 
        a: &dyn SelectableNode<T>, 
        b: &dyn SelectableNode<T>
    ) -> Ordering;
}

This trait defines an heuristic to rank the nodes in order to remove (or merge) the less relevant ones from an MDD that is growing too large.

Required methods

`fn compare( &self, a: &dyn SelectableNode<T>, b: &dyn SelectableNode<T> ) -> Ordering`

Defines an order of 'relevance' over the nodes a and b. Greater means that a is more important (hence more likely to be kept) than b.
