Re: Gross Bug in Simplify


Hi,
if you slightly modify the upvalue it works:


In[1]:= f[u__]^v_ ^:= f[u] /; v > 0;   $Version

Out[1]= 4.1 for Linux (November 2, 2000)

In[2]:= Simplify[{1 - f[4], 1 - 7 f[4], 1 + f[4], 1 - x f[4]}]

Out[2]= {1 - f[4], 1 - 7 f[4], 1 + f[4], 1 - x f[4]}


But yes, the bug you found is pretty bad.

Why don't you ask Wolfram Research to become a beta tester of the
next version and then you can check if things are fixed there.
They always like good bug reports and in general they fix the bugs.
Reality seems to be however that there is no bug-free software.

Regards,

Rolf Mertig
