Dear Group,
Here are very strange rezults from
RplaceRepeated.
Input:
tarp=List[
List[AuxVertex[List[List[i2],m2]],
CG[List[i1,m1],List[i2,m2],List[i3,F[m3]]],
WD[i1,List[List[m1],List[m2]],List[q0]]],
List[AuxVertex[List[List[i1],m1]],
CG[List[i1,m1],List[i2,m2],List[i3,F[m3]]],
WD[i1,List[List[m1],List[m2]],List[q0]]]]
Now try this on Linux box:
tarp//.{F[_]:>S[Infinity],_?NumberQ:>S[Infinity]}
It rezults in infinite loop. Using TracePrint indicates, that
somewhere integer "1" appears for which NumberQ gives True. But there
isn't '1' at all in tarp! What is happening here?
