This TRS is terminating using the restricteddeltasimple interpretation 
++(delta3, X2, X1) =  + 1*X1 + 1*X2 + 1 + 0*X1*delta3 + 0*X2*delta3 + 0*delta3
b(delta2) =  + 1 + 0*delta2
rev(delta1, X0) =  + 1*X0 + 0 + 1*X0*delta1 + 0*delta1
a(delta0) =  + 1 + 0*delta0
++_tau_1(delta3) =  + (delta3/(1 + 0 * delta3))
