YES

This TRS is terminating using the restricteddeltasimple interpretation 
g(delta3, X1) =  + 0*X1 + 0 + 1*X1*delta3 + 0*delta3
a(delta2) =  + 1 + 0*delta2
b(delta1) =  + 0 + 2*delta1
f(delta0, X0) =  + 0*X0 + 0 + 3*X0*delta0 + 0*delta0
g_tau_1(delta3) =  + (delta3/(0 + 1 * delta3))
f_tau_1(delta0) =  + (delta0/(0 + 3 * delta0))
