Hi Mathematica Community,
First,wish you happy and successfull new year.
For this 2nd problem in the same subject,I have this system to solve:
Reduce[Not[
ForAll[{aaP, abP, iP, jP, sP, tP, uP, xP, yP, zP},
Implies[t == tP && i + x == iP + xP && y == yP &&
j t + z == jP tP + zP && t x + z == tP xP + zP &&
Floor[Log[j]/Log[2]] == Floor[Log[jP]/Log[2]] &&
Floor[Log[x]/Log[2]] == Floor[Log[xP]/Log[2]] && x >= xP,
t x == tP xP]]]]
in mathematica 5 the output is given in a very short time and is "the
system cannot be solved with the method available to Reduce" this
suits me (although I wish it to be the output "True" which is the
right answer)
in mathematica 8 the kernel still in running indefinitely and this
does not suit me at all :(
so how to deal with that?
