YES

This TRS is terminating using the restricteddeltasimple interpretation 
f(delta2, X1) =  + 0*X1 + 1 + 1*X1*delta2 + 1*delta2
0(delta1) =  + 0 + 0*delta1
s(delta0, X0) =  + 0*X0 + 1 + 3*X0*delta0 + 0*delta0
f_tau_1(delta2) =  + (delta2/(0 + 1 * delta2))
s_tau_1(delta0) =  + (delta0/(0 + 3 * delta0))
