### Does the Halting Problem prove that true Artificial Intelligence is impossible?

The Halting Problem demonstrates that there are things that a machine can never be programmed to do. Is this proof that true Artificial Intelligence - that is, the ability for a machine to think and ...

### How does an admissible heuristic ensure an optimal solution?

When using A* (or any other best path finding algorithm), we say that the heuristic used should be admissible, that is, it should never overestimate the actual solution path's length (or moves). How ...

### Are expert systems outdated, what are better alternatives to them, if any?

I need to link facts to actions through rules. If a person bought soup 10 times and he is coming at midday every day, then the system should link the fact that the person bought soup so many times, ...

### What would show a human mind is/is not reducible to a Turing machine?

In computer science it is often assumed that a human mind can be reduced to a Turing machine. This is the assumption that underlies the field of artificial intelligence. However, it is an assumption,...

### Are genetic algorithms an effective way to train neural networks?

It seems to me that genetic algorithms would be an ideal way to train neural networks so that they come to have the right weights, since they are especially good at escaping local minima, and ...

### Why can't humans translate all of their abilities into an algorithm? Will that hold true in the future?

I know that an algorithm can't decide whether another algorithm halts on an input or not (a Turing machine can't decide whether another Turing machine will halt on an input). But I, as an human, can: ...
