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.

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

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(4709_0_ITER_LOAD(x1, x2, x3)) = x3 + [-1]x1   
POL(COND_4709_0_ITER_LOAD2(x1, x2, x3, x4)) = [-1] + x4 + [-1]x2 + [-1]x1   
POL(&&(x1, x2)) = 0   
POL(<(x1, x2)) = [-1]   
POL(<=(x1, x2)) = [-1]   
POL(0) = 0   
POL(+(x1, x2)) = x1 + x2   
POL(*(x1, x2)) = x1·x2   
POL(3) = [3]   
POL(-1) = [-1]

COND_4709_0_ITER_LOAD2(TRUE, x1[5], x2[5], x0[5]) → 4709_0_ITER_LOAD(x1[5], x2[5], +(x0[5], -1))

The following pairs are in P≥:

COND_4709_0_ITER_LOAD2(TRUE, x1[5], x2[5], x0[5]) → 4709_0_ITER_LOAD(x1[5], x2[5], +(x0[5], -1))

At least the following rules have been oriented under context sensitive arithmetic replacement:
