YES

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