What on earth are you talking about? The deterministic algorithm behaves as
it does for a reason but does not do so for a reason??!!

If it depends on something then it's deterministic.

Not unless your meaning of "powerful" is radically diferent from mine.

Are you really quite sure of that? The computer I'm typing this on is an
ancient iMac that was not top of the line even back a full Moore's Law
generation ago when it was new, back in the olden bygone days of 2011. Like
all computers the number of floating point operations per second it can
perform depends on the problem, but in computing dot products running
multi-threaded vector code it runs at 34.3 GFOPS; so Deep Blue running at
11.38 GFLOPS doesn't seem as impressive as it did in 1997.

Right now the fastest supercomputer in the world has a LINPACK rating of
54.9 pentaflop*s, a *pentaflop IS A MILLION GFLOPS; so today that Chinese
supercomputer is 4.8 millions times as powerful as Deep Blue was in 1997.
And in just a few years that supercomputer will join Deep Blue on the
antique computer junk pile.
