This TRS is terminating using the deltasimple interpretation 
c(delta4) =  + 0 + 0*delta4
b(delta3) =  + 1 + 1*delta3
g(delta2, X2) =  + 1*X2 + 0 + 1*X2*delta2 + 0*delta2
a(delta1) =  + 1 + 1*delta1
f(delta0, X1, X0) =  + 1*X0 + 1*X1 + 0 + 1*X0*delta0 + 0*X1*delta0 + 0*delta0
g_tau_1(delta2) =  + (delta2/(1 + 1 * delta2))
f_tau_1(delta0) =  + (delta0/(1 + 0 * delta0))
f_tau_2(delta0) =  + (delta0/(1 + 1 * delta0))
