This TRS is terminating using the restricteddeltasimple interpretation 
g(delta2, X4, X3) =  + 0*X3 + 1*X4 + 0 + 1*X3*delta2 + 3*X4*delta2 + 0*delta2
h(delta1, X2, X1) =  + 0*X1 + 1*X2 + 0 + 1*X1*delta1 + 3*X2*delta1 + 2*delta1
f(delta0, X0) =  + 1*X0 + 1 + 0*X0*delta0 + 0*delta0
g_tau_1(delta2) =  + (delta2/(1 + 3 * delta2))
g_tau_2(delta2) =  + (delta2/(0 + 1 * delta2))
h_tau_1(delta1) =  + (delta1/(1 + 3 * delta1))
h_tau_2(delta1) =  + (delta1/(0 + 1 * delta1))
f_tau_1(delta0) =  + (delta0/(1 + 0 * delta0))
