We consider the following Problem:
Strict Trs:
{ g(s(f(x))) -> g(f(x))
, g(c(x, s(y))) -> g(c(s(x), y))
, f(c(s(x), y)) -> f(c(x, s(y)))}
StartTerms: all
Strategy: none
Certificate: YES(?,O(n^1))
Proof:
The problem is match-bounded by 1.
The enriched problem is compatible with the following automaton:
{ s_0(1) -> 1
, s_1(1) -> 3
, s_1(3) -> 3
, c_0(1, 1) -> 1
, c_1(1, 3) -> 4
, c_1(3, 1) -> 2
, f_0(1) -> 1
, f_1(1) -> 2
, f_1(4) -> 1
, f_1(4) -> 2
, g_0(1) -> 1
, g_1(2) -> 1}

QUADRATIC upper bound on the derivational complexity
This TRS is terminating using the deltarestricted interpretation
g(delta, X0) = + 1*X0 + 0 + 3*X0*delta + 0*delta
s(delta, X0) = + 1*X0 + 1 + 0*X0*delta + 2*delta
c(delta, X1, X0) = + 1*X0 + 0*X1 + 0 + 0*X0*delta + 2*X1*delta + 0*delta
f(delta, X0) = + 0*X0 + 0 + 1*X0*delta + 0*delta
g_tau_1(delta) = delta/(1 + 3 * delta)
s_tau_1(delta) = delta/(1 + 0 * delta)
c_tau_1(delta) = delta/(0 + 2 * delta)
c_tau_2(delta) = delta/(1 + 0 * delta)
f_tau_1(delta) = delta/(0 + 1 * delta)
