Except A0 has demonstrated that one particular approach works reasonably well, so they aren't starting at some random unknown.
I wouldn't go so far as to say that. All we know is that it worked. But ...

The strategy you advocate is fundamentally flawed. The point is that different network topologies might have wildly different performance. In such a situation it pays to try things in parallel. Suppos ...

So the ressources poured into the experiment are never wasted.
It depends on how you define 'wasted'. Confirming results by others in general only helps to secure the fame for those others, and doesn ...

As long as you store the depth to which you are comparing on a probe, (i.e. both before or after the extension) there is no problem. Whether you are in check or not isn't path dependent. I usually sto ...
