Numerical software? What kind of numerical software you are talking
about?




Maybe it would be intersting to know your definition of "numerical software"...


Yes. We have the same question!

Okay. I thought we were talking about code like SLATEC, NSWC, CMLIB, etc. They have (almost) nothing to do with algorithms to find subsets, which I would classify with discrete or combinatorics algorithms.

It's easy to write poor numerical algorithms (with my definition),
the usual example is "Numerical Recipes", but I find much more
difficult to write *good* (read /accrurate and fast/) ones. Just
try to write a correctly rounded sine (or even a square root !).

'Jaap' is pronounced (in Dutch) as 'ya' from 'yard' followed by a 'p'
from'cap' (phonetic: ja.p).
'Spies' sounds like an 's' followed by the word 'peace' (spi:s).
