Subject [jira] [Commented] (MATH-1137) BOBYQA incorrect indexing
Date Sun, 05 Oct 2014 18:49:34 GMT

] commented on MATH-1137:

I am 99% sure that my suggested corrections are correct, but this issue is not amenable to
unit tests. I have done various tests, and none of them so far go through the relevant lines
of code, so I can't check whether my changes work or not, nor their effect.

That is the nature of complex code like this.

I can't even find where in the original paper the relevant code relates to.

So this is a case of testing by reading the code, not testing by unit tests.

I have retained my personal copy of the code which contains the corrections, and cannot afford
any more time on this.

All I can ask is for others to look through my suggested changes and check them by reading
