Ladders sound hard for neural networks. IIRC the original AlphaGo had a ladder-solver hardcoded that would determine if a ladder position is winning or losing and feed this bit into the neural network.
- thomasahle 9y agoI'm pretty sure it didn't, though I can't find it explicitly for Alpha Go. For Zero they specifically mention that it took the self playing a long time to learn ladders well.
- espadrine 9y agoI can confirm that the original 2015 Nature paper for AlphaGo mentions setting ladder capture / ladder escape bits as input to the neural network. cf. https://gogameguru.com/i/2016/03/deepmind-mastering-go.pdf https://gogameguru.com/i/2016/03/deepmind-mastering-go.pdf, Extended data table 2
