What evidence would it take for you to change your mind?

[Mark Knowles]

I recollect that we have developed (or at least intended to develop - which is already half the work, of course) a series of tests which must be passed by any would-be solution to be seriously considered a "solution".

I think there was a dedicated thread in the forum.

My favourite tests are limited in scope but (I believe) very efficient. They are:

the otol test

and

the aror sheey test.

Namely, given one's solution, translate those vords and see if you are to the point.

I have developed a test.
