(7) TempFilterProof (SOUND)
Used the following sort dictionary for filtering:

----------------------------------------

(9) PolynomialOrderProcessor (EQUIVALENT)
Found the following polynomial interpretation:
[f137_0_test_GE(x, x1)] = x1

The following rules are decreasing:
f137_0_test_GE(x3:0, x1:0) -> f137_0_test_GE(c, x3:0) :|: c = 0 && (x3:0 <= x1:0 - 1 && x1:0 > 0)
The following rules are bounded:
f137_0_test_GE(x3:0, x1:0) -> f137_0_test_GE(c, x3:0) :|: c = 0 && (x3:0 <= x1:0 - 1 && x1:0 > 0)
f137_0_test_GE(x4:0, x5:0) -> f137_0_test_GE(c1, x5:0) :|: c1 = x4:0 + 1 && (x5:0 - 1 >= x4:0 && x5:0 > 0)

----------------------------------------

f137_0_test_GE(x4:0, x5:0) -> f137_0_test_GE(c1, x5:0) :|: c1 = x4:0 + 1 && (x5:0 - 1 >= x4:0 && x5:0 > 0)

----------------------------------------

(11) RankingReductionPairProof (EQUIVALENT)
Interpretation:
[ f137_0_test_GE ] = f137_0_test_GE_2 + -1*f137_0_test_GE_1

The following rules are decreasing:
f137_0_test_GE(x4:0, x5:0) -> f137_0_test_GE(c1, x5:0) :|: c1 = x4:0 + 1 && (x5:0 - 1 >= x4:0 && x5:0 > 0)

The following rules are bounded:
f137_0_test_GE(x4:0, x5:0) -> f137_0_test_GE(c1, x5:0) :|: c1 = x4:0 + 1 && (x5:0 - 1 >= x4:0 && x5:0 > 0)
