I'm probably not the best judge of whether it is "notable" enough for
Wikipedia. I certainly would not be the best person to discuss
Heathfield's Law from a neutral point of view. (Having said that, I
ought to give some thought to formalising the wording, just in case...)
But that's not why I'm replying! Rather, I have a data point from
today's trawl through the design ocean, that I think is relevant to the
discussion regarding recursion vs iteration.
Today I encountered a problem that is, I think, isomorphic to the
following problem statement:
I have sixteen elements, evenly divided into metals M and non-metals N,
so there are eight elements in each group. We'll call them M[0] to M[7]
and N[0] to N[7].
A molecule consists of 0 or more diatoms { M[a], N[b] } (i.e. a metal
and a non-metal) where a is in the range [0,7] and b in the range [0,6],
terminated by a diatom { M[a], N[7] }.
My problem is that I need to construct all possible molecules containing
a given number of diatoms.
It seemed to me that this was an obvious case for iteration, and I spent
about two hours trying to write a clear, correct function that did the
job. I have no doubt that this is possible, but I couldn't see a way to
do it. Eventually, I gave up, sat back, and thought it through some more
(without result). Time for coffee. And then, without warning, the easy
way jumped out at me. Down went the cup, and in went the code, which
took just a few minutes. So that you don't have to wade through a whole
bunch of housekeeping code, I'll show it here in pseudo-C:
print_set(molecule)
{
for(i = 0; i < M_COUNT; i++)
{
diatom = get_terminal_diatom(i);
print(molecule, diatom, newline);
}
}
gen_atom(molecule, length)
{
if(length == 0)
{
print_set(molecule);
}
else
{
lim = M_COUNT * NTNM_COUNT; /* NTNM=Non-Terminal Non-Metal */
for(mn = 0; mn < lim; mn++)
{
diatom = get_nonterminal_diatom(mn);
gen_atom(molecule + diatom, length - 1);
}
}
}
Now I can generate a complete set of molecules of any (reasonable)
length n+1 using gen_atom("", n); (where n is the number of non-terminal
diatoms).
Obviously it's not quite that neat in reality, because there's a bunch
of string-building going on, which I've handwaved into '+' in the above
pseudo-C, but the essence of the idea is shown above, and it's
remarkably simple. The actual code is a bit longer, but it's still much,
much shorter than the iterative version (the version that didn't work).
Sometimes, recursion is just better. (That doesn't mean it always is!)
