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

TOP(mark(0)) → c28(TOP(ok(0)))

We considered the (Usable) Rules:

div(mark(z0), z1) → mark(div(z0, z1))
active(if(z0, z1, z2)) → if(active(z0), z1, z2)
minus(ok(z0), ok(z1)) → ok(minus(z0, z1))

active(geq(0, s(z0))) → mark(false)
active(minus(s(z0), s(z1))) → mark(minus(z0, z1))

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

TOP(mark(false)) → c28(TOP(ok(false)))

We considered the (Usable) Rules:
