Required Methods§

Source

fn estimate( &mut self, rnd: &mut ChaCha8Rng, config: &MCTSConfiguration, initial_state: &D::State, start_tick: u64, node: &Node<D>, edges: &Edges<D>, depth: u32, ) -> Option<BTreeMap<AgentId, f32>>

Takes the state of an explored node and returns the estimated expected (discounted) values.

Returns None if the passed node has no unexpanded edge.
