Re: P1788: PLEASE VOTE: M0013.04 & M0020.01



John,

My error.  M0020.01:Comparing_comparisons, moved by Dominique Lohez

on which you had written:

I forgot to give my reasons to vote NO on Dominique Lohez's "frameWorkForComparisonRelations" paper.

As a pure mathematician, I like its contents a lot. As a mathematician trying to do software engineering, I think it goes beyond what anyone writing practical interval software needs.
- Arnold says he only ever needed 3 comparisons.
- Baker concurs, though admitting his applications were similar to Arnold's.
- Someone said the Kulisch <= is used in branch-and-bound to rank candidates: that makes 4.

No one else has offered evidence of uses in actual interval code. So for sake of KISS I vote against.
