Strict Trs:
{ bits(s(x)) -> s(bits(half(s(x))))
, bits(0()) -> 0()
, half(s(s(x))) -> s(half(x))
, half(s(0())) -> 0()
, half(0()) -> 0()}

Certificate: TIMEOUT
Proof:
Computation stopped due to timeout after 60.0 seconds.

We consider the following Problem:
Strict Trs:
{ bits(s(x)) -> s(bits(half(s(x))))
, bits(0()) -> 0()
, half(s(s(x))) -> s(half(x))
, half(s(0())) -> 0()
, half(0()) -> 0()}
StartTerms: all
Strategy: none
Certificate: YES(?,O(n^3))
Proof:
We have the following EDA-non-satisfying matrix interpretation:
Interpretation Functions:
0() = [3]
[1]
[1]
half(x1) = [1 0 0] x1 + [1]
[0 0 1] [1]

[0 1 0] [2]
[0 1 0] [0]
Hurray, we answered YES(?,O(n^3))Tool IDA
