The constraints for P> respective Pbound are constructed from P where we just replace every occurence of "t ≥ s" in P by "t > s" respective "t ≥ c". Here c stands for the fresh constant used for Pbound.
Using the following integer polynomial ordering the resulting constraints can be solved
Polynomial interpretation over integers[POLO]:

POL(TRUE) = 0   
POL(FALSE) = 0   
POL(1716_0_CREATEINTLIST_LE(x1)) = [2]x1   
POL(COND_1716_0_CREATEINTLIST_LE(x1, x2)) = [2]x2   
POL(>(x1, x2)) = [-1]   
POL(0) = 0   
POL(+(x1, x2)) = x1 + x2   
POL(-1) = [-1]   

The following pairs are in P>:

COND_1716_0_CREATEINTLIST_LE(TRUE, x0[1]) → 1716_0_CREATEINTLIST_LE(+(x0[1], -1))

The following pairs are in Pbound:

1716_0_CREATEINTLIST_LE(x0[0]) → COND_1716_0_CREATEINTLIST_LE(>(x0[0], 0), x0[0])

The following pairs are in P:

1716_0_CREATEINTLIST_LE(x0[0]) → COND_1716_0_CREATEINTLIST_LE(>(x0[0], 0), x0[0])
