AlphaGo is a hybrid system, using deep reinforcement learning and Monte Carlo tree search. Tree search dates back to Shannon, before neural networks. AlphaGo is a triumph of symbolic as well as statistical AI.

Indeed, the objection is against the method by which this system is supposed to be defined. As you say, we start with an implicit assumption that we don’t have an effective procedure to construct the set of statements that are true in th

You may be working in classical logic, but that doesn’t mean the parent poster is. You asserted the parent poster seems to be confused, but what the parent poster said makes sense in a constructive setting. Please see my other comment: h

You seem to be forgetting that constructive truth means provability. Also, it doesn’t seem right to use the informal “take” when the object in question is not computable.

You are invoking a classical notion of existence. This is not acceptable to a constructivist, for whom “a statement is true if we have a proof of it, and false if we can show that the assumption that there is a proof for the statement l

Two sentence summary that glosses over a lot of things: 1. Types can be used to classify programs. 2. Dependent types can be used to classify programs by running other programs on them. If you would like to learn more about dependent types,
