This TRS is terminating using the deltarestricted interpretation 
mark(delta4, X3) =  + 1*X3 + 0 + 1*X3*delta4 + 2*delta4
a(delta3) =  + 0 + 0*delta3
f(delta2, X2) =  + 1*X2 + 3 + 3*X2*delta2 + 0*delta2
g(delta1, X1) =  + 0*X1 + 0 + 2*X1*delta1 + 1*delta1
a__f(delta0, X0) =  + 1*X0 + 3 + 3*X0*delta0 + 1*delta0
mark_tau_1(delta4) =  + 1(delta4/(1 + 1 * delta4))
f_tau_1(delta2) =  + 1(delta2/(1 + 3 * delta2))
g_tau_1(delta1) =  + 1(delta1/(0 + 2 * delta1))
a__f_tau_1(delta0) =  + 1(delta0/(1 + 3 * delta0))
