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

AND(mark(z0), z1) → c9(AND(z0, z1))
We considered the (Usable) Rules:none
And the Tuples:

ISNEPAL(ok(z0)) → c4(ISNEPAL(z0))
ISNEPAL(mark(z0)) → c5(ISNEPAL(z0))
__'(z0, mark(z1)) → c6(__'(z0, z1))
__'(ok(z0), ok(z1)) → c7(__'(z0, z1))
__'(mark(z0), z1) → c8(__'(z0, z1))
AND(mark(z0), z1) → c9(AND(z0, z1))
AND(ok(z0), ok(z1)) → c10(AND(z0, z1))
TOP(mark(z0)) → c1(TOP(proper(z0)))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(AND(x1, x2)) = x1   
POL(ISNEPAL(x1)) = 0   
POL(TOP(x1)) = 0   
POL(__'(x1, x2)) = 0   
POL(c1(x1)) = x1   
POL(c10(x1)) = x1   
POL(c4(x1)) = x1   
POL(c5(x1)) = x1   
POL(c6(x1)) = x1   
POL(c7(x1)) = x1   
POL(c8(x1)) = x1   
POL(c9(x1)) = x1   
POL(mark(x1)) = [1] + x1   
POL(nil) = 0   
POL(ok(x1)) = x1   
POL(proper(x1)) = 0   
POL(tt) = 0
