For the full standard library qsort() replacements (that use external
compare routines and are passed data item length) the switch point is
7 elements.
For a routine optimised for char data it was fairly high - I saw
improvements in sort time up to 40, but I suspect it is sensitive to
total sort length.
For short data 13 to 18 gave the same time - so probably 15 would be
optimum.
For long data 9 to 11 gave the same time - so 10 is optimum in that

You should have! Richard has it on DoNoR/2 so you have no excuse... :-)
Some of the code in there is interesting in it's alternative approaches.
The generic qsort() routine maintains an internal stack to control
recursion, which is much faster than true recursion as it only involves
storing two variables and updateing the stack offset (pointer) variable
rather than the full overhead of a function call.
There are, inevitably, some lapses from optimum codeing practise. eg the
specialised version of quicksort for int data calls an external routine
to swap elements. By declaring the transfer temporary variable in the
main sort routine and using a macro for the swap the clarity of code
presentation can be maintained while achieving a measureable improvement
in sort speed.

Hi George,
Ok, I'll download a copy of SNIPPETS tomorrow night.
You are getting a little ahead of the code I am posting in C_PlusPlus here.
I was going to post the non-recursive Quickersort after I had posted the
median-of-three version.
Rather nasty, calling a subroutine to perform 3 machine instructions.

Hi Tom,
[snip]
Ugh! That has even more iterations than genuine bubble sort.
This is _guaranteed_ to perform n**2 comparisons, even when the data are
already ordered. That is twice as slow as bubble sort's worse case.
If you want to keep your code small (actually make it smaller), as well as
reducing the sort's run time by 75%, replace the above code with Insertion
sort. More sophisticated algorithms will reduce run time even more.
Yes.
It doesn't have one, AFAIK, as nobody would bother formally publishing an
algorithm that is so sub-optimal. We could call it 'dirigible sort' or
'Zeppelin sort' if you like. ... :-)
Try Shellsort, as posted in the C_PlusPlus echo. You can instantiate the
template by hand, simply by replacing the capital T with the type of "thing"
you are sorting and, where necessary, using strcmp(), memcmp(), etc.,
instead of the comparison operator.

Hi George,
That is a reasonable figure, especially for older Intel CPU's that had
poorer microcode for string instructions.
It would be very sensitive to key length. For short strings you could,
perhaps, get away with more. For longer strings, I would limit Insertion
sort to rather fewer than 40. As above, about 7 or 8.
Very plausible.
Very plausible, again.
On a CPU with very fast FPU hardware, this would likely be good for floating
point numbers, too. With a slower FPU (e.g. 80387 or earlier) I would keep
it down a couple more.

SmackUser() within a suitable loop which could also determine if the User has

while (UserState != SufficientSmacking)

Note the continued use of SmackUser() until he/she reaches a predetermined

assistant: Hi Roger,
I'm still pretty new at C but have been around computers for a little while
now. ;-)  The first serious tests I ever did with sorting was when writing an
assembler for the Commodore 8 bit machines (before the PC was born). Trying
to sort a symbol table with variable length symbols on such slow machines
means you try everything you can to make it go as fast a possible. Once I got
near making a final decision it came down to counting machine cycles because
there was no other practical way to time it. I can't be bothered going to
that level any more though. :-)
Newbie. ;-) I thought you'd been at it longer than that.
Exactly. It was (relatively) fast when first developed but no longer stands
p
to the competition for general use. Note: *All* sorts have performance
advantages under certain conditions but these known conditions are seldom
found
in real-world applications.
Sorting really is a fascinating subject. When you do your tests strip the
sorting routine out of F-tags and check it out. If you come up with something
better for general use please let me know.

assistant: Yes, we are. But I've yet to see anything resembling that from you.
Instead, I've seen insults (public insults, at that). Of VIDMGR, you said
you "really expected better", etc. Of MultiMail, and now again with
VIDMGR, you spoke of "poor programming practice". Such remarks have no
place in any bug report.
And again, if you hate it, why do it? Such a grudging contribution is
hardly going to be welcomed.
I do. Here's a guy who busts his ass on some code, which he then makes
available for free, and all you can do is complain about how you "expected
better". I found that offensive.
However, readers of the OFFLINE echo will be aware that my reaction was
not entirely based on that one comment here, but also on certain flame
wars you began there. I realize I should keep them separate, but when I
saw the same pattern here, it really got to me.
Eh?
Forgive my skepticism. I don't pretend to have examined the VIDMGR code
myself. But based on your shallow and erroneous analysis of MultiMail in
OFFLINE, I knew that you were given to making poor assumptions, and not
really studying the code.
If it works correctly on the original platform, then it's not a bug *in
the original code*. It may not be portable, as written -- but did it ever
promise to be? Dealing with bugs that arise *only* in the port is part of
porting it -- not debugging it. Or, call it debugging the port; but it's
not fair to call it a bug in the original.
Your ASSumptions are showing. Again. I have about 16 years of programming
experience myself. (I admit, I'm relatively new to C... but I don't think
that's relevant to this, um, discussion.)

What you've done is not to declare a structure within itself, but rather a
*pointer* to a structure of that type. Storage must be allocated to those
pointers manually, via "malloc" (for C) or "new" (for C++). That's how
lists are built.
Since they're only pointers, not structures, there's no automatic
