Termination Proof Script

Consider the TRS R consisting of the rewrite rules
1:    minus(0)  → 0
2:    x + 0  → x
3:    0 + y  → y
4:    minus(1) + 1  → 0
5:    minus(minus(x))  → x
6:    x + minus(y)  → minus(minus(x) + y)
7:    x + (y + z)  → (x + y) + z
8:    minus(x + 1) + 1  → minus(x)
There are 6 dependency pairs:
9:    x +# minus(y)  → MINUS(minus(x) + y)
10:    x +# minus(y)  → minus(x) +# y
11:    x +# minus(y)  → MINUS(x)
12:    x +# (y + z)  → (x + y) +# z
13:    x +# (y + z)  → x +# y
14:    minus(x + 1) +# 1  → MINUS(x)
The approximated dependency graph contains one SCC: {10,12,13}.
