It dawned on me last night something I have not
been reading that I would expect to be very common.
That is comments on the source code to the effect "this
algorithm is faster than the one uses in POV." Are they
in a newsgroup I don't read? Am I blinkd? Are the
algorithms from some accepted standard package? Not
that I want to get involved in that kind of thread.

Not exactly comment's on the source code but rendering algorithms in
general.
If you want to read something like that, go to:

computer.graphics.rendering.raytracing

If you like some spam, and a hot flame now and then is almost perfect.
You will also meet some names that show up here quite often.

You can ask anyone using any other renderer other than povray and he can
tell you some algorithm that is faster than the one used in povray.
  I doubt that most of them have ever tried.

    Thanks but was just asking.

    I only deal with political flames, thank you. I was just curious as to
what I was not seeing. Algoritmic solutions bothre me when they slow down
my programs.

    I was recognizing the "battle of the algorithms" that is so common. Just
noting I had not seen those battles over POV source.

    And since I am finally getting into C directly hoping there was some
optimized library as for FORTRAN that no one seriously debates.

Nobody bothers to boast that they have an algorithm faster than ray
tracing, since ray tracing optimizes for realism rather than speed and
ends up being the slowest 3-D rendering algorithm out there (except for
radiosity and hybrid radiosity/ray tracing, the latter of which is
supported after a fashion in POV-Ray).  If you want speed, pick a
different algorithm.

There are ways to provide speed improvement to ray tracing algorithms,
mostly involving exploiting some sort of coherence (bounding, light
buffer, vista buffer, etc.).  POV-Ray has implemented most of those over
the years.

I have no understanding of this question.

My reply, however, would be this:

"1+1=2"

You can quote me on this.

p.s.
My understanding of algorithms is limited, at best.
I appreciate your questioning of this.

Your blindness[sic] on this issue is shared by me.
I could only hope that our two divergence viewpoints
could somehow verge to a point which would advance
POV.

This would be my hope.
As for another thread, I could only say,
"Oh, no"
