<pre><span class="quote">> The output domain seems wrong, n shouldn't be { [] } universe. The counter cases are, when i0 is 0, n should be <= 2; when i0 is -1, if n is -1, the condition "4i0 >= -2 + n" doesn't satisfied; ...</span >
After projecting out, the remaining [] is in the set, if there exists one i0
such that the condition is satisfied. For each n I can find an i0 such that the
condition is fulfilled, e.g.
i0 = (n <= -2) ? -1 : [-1/2 + 1/4*n]
That is, you choose i0 after n is fixed, not the other way around.
Btw, for isl-only questions, there is a mailing list:
