(17) CdtRuleRemovalProof (UPPER BOUND(ADD(n^1)) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

TOP(mark(z0)) → c1(TOP(proper(z0)))
We considered the (Usable) Rules:

proper(0) → ok(0)
And the Tuples:

AFTER(z0, mark(z1)) → c2(AFTER(z0, z1))
AFTER(ok(z0), ok(z1)) → c3(AFTER(z0, z1))
AFTER(mark(z0), z1) → c4(AFTER(z0, z1))
FROM(ok(z0)) → c5(FROM(z0))
FROM(mark(z0)) → c6(FROM(z0))
S(ok(z0)) → c7(S(z0))
S(mark(z0)) → c8(S(z0))
CONS(ok(z0), ok(z1)) → c9(CONS(z0, z1))
CONS(mark(z0), z1) → c10(CONS(z0, z1))
TOP(mark(z0)) → c1(TOP(proper(z0)))
The order we found is given by the following interpretation:
