Sorry, just realized the my last modifications were logically incorrect.
Having the newpath variable is essential.

On my laptop, your Viterbi benchmark runs in 6.9s, and this new
implementation runs in 0.5s, so it's something like 14x faster. If you
wanted to push on performance any more, I'd

Hi Jason,
Thanks for this and your previous comment.
I might play about with this some more myself, e.g. back translate to
Python to compare again.
Note that the

Python w/ numba and Julia are comparable in speed for the tests I did. This
is
not surprising as numba utilizes LLVM as well. For the above example and on
my
Unix computer, the timings are 15 ms for Python+numba and 20 ms for Julia.

It depends on the coming algorithm. 1000 points is not very much; the whole

One thing that's really nice about Julia is that it's often straightforward
to transliterate python code (or matlab code) in a fairly literal way and
end up with working code that has similar, or sometimes better performance.
But another nice thing about Julia is that it allows you to fairly
