Struct EntityTabuAcceptor 

pub struct EntityTabuAcceptor { /* private fields */ }

Entity tabu acceptor - maintains a tabu list based on entity identifiers.

This is a more sophisticated tabu search that tracks which entities have been recently modified rather than just tracking scores. It requires entities to have a stable hash/identifier.

Example

use solverforge_solver::phase::localsearch::EntityTabuAcceptor;

let acceptor = EntityTabuAcceptor::new(7);
assert!(!acceptor.is_entity_tabu(42));

Implementations

impl EntityTabuAcceptor

pub fn new(entity_tabu_size: usize) -> Self

pub fn record_entity_move(&mut self, entity_id: u64)

Records that an entity was moved in the current step.

pub fn is_entity_tabu(&self, entity_id: u64) -> bool

Returns true if the given entity is in the tabu list.
