hugs #of reductions

[Ch. A. Herrmann]

Hi!

We observed that often the evaluation of the same expression again
requires fewer reductions than before.

It seems that the number of reductions hugs reports (:set +s)
does not only depend on the program loaded and the expression
evaluated but also on other things. What are they?

Is there a way to produce deterministic results; e.g.,
does a freshly loaded hugs on the same machine with
the same program and evaluated expression always
deliver the same number of reductions?

Cheers
