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(304_0_MAIN_LOAD(x1, x2)) = [1] + x2 + x1   
POL(0) = 0   
POL(COND_304_0_MAIN_LOAD(x1, x2, x3)) = [1] + x2   
POL(>(x1, x2)) = [-1]   
POL(+(x1, x2)) = x1 + x2   
POL(-1) = [-1]   
POL(COND_304_0_MAIN_LOAD1(x1, x2, x3)) = [1] + x3 + x2   
POL(&&(x1, x2)) = [-1]   
POL(<(x1, x2)) = [-1]   

The following pairs are in P>:

COND_304_0_MAIN_LOAD(TRUE, x1[1], 0) → 304_0_MAIN_LOAD(+(x1[1], -1), 0)
COND_304_0_MAIN_LOAD1(TRUE, x1[3], x0[3]) → 304_0_MAIN_LOAD(x1[3], +(x0[3], -1))

The following pairs are in Pbound:

304_0_MAIN_LOAD(x1[0], 0) → COND_304_0_MAIN_LOAD(>(x1[0], 0), x1[0], 0)
304_0_MAIN_LOAD(x1[2], x0[2]) → COND_304_0_MAIN_LOAD1(&&(&&(>(x1[2], -1), >(x0[2], 0)), <(0, +(x0[2], x1[2]))), x1[2], x0[2])

The following pairs are in P:

304_0_MAIN_LOAD(x1[0], 0) → COND_304_0_MAIN_LOAD(>(x1[0], 0), x1[0], 0)
304_0_MAIN_LOAD(x1[2], x0[2]) → COND_304_0_MAIN_LOAD1(&&(&&(>(x1[2], -1), >(x0[2], 0)), <(0, +(x0[2], x1[2]))), x1[2], x0[2])

There are no usable rules.
