Re: position paper on comparisons
Dear Juergen and Marco,
like Baker I also think that you may do well to
write a summary of the possible impact of your
position paper on Motion 13.
I have a few terminological comments, questions
and suggestions.
1. It seems strange that you call mapping (1) a
relation. Moreover you call it "interval overlapping
relation". Why? This name suggests a link to relations
"overlapLeft" and "overlapRight". Yet these
relations are just two of the cases in mapping (1).
Do you want to susggest that the order relation "overlapLeft"
is "basic" in some sense? It is well-known that this
relation is of little (or no) importance for interval analysis,
both in theory and applications. To my knowledge it
does not play a special role in J. F. Allen's boolean
algebra of temporal intervals either.
2. It seems to me that your position paper concerns
implementation layers 3 and 4, is this correct? If so,
your position paper has little or no impact on Motion 13,
is this so?
I think that your position paper would become more
useful, if it includes:
i) a presentation of all order relations enlisted in
Table 2 by means of the four basic order relations as
given in Motion 13 (improved by remarks made by Nate
Hayes and Michel Hack);
ii) an alternative approach for implementation that is
based on Kulisch's four basic order relations;
iii) a comparison beween the two approaches w.r.t.
effective implementation.
Regards,
Svetoslav
