YES

This TRS is terminating using the restricteddeltasimple interpretation 
d(delta9) =  + 0 + 0*delta9
f(delta8, X5, X4) =  + 0*X4 + 0*X5 + 0 + 1*X4*delta8 + 1*X5*delta8 + 0*delta8
a(delta7) =  + 1 + 0*delta7
b(delta6) =  + 0 + 3*delta6
g(delta5, X3) =  + 0*X3 + 0 + 4*X3*delta5 + 0*delta5
f_tau_1(delta8) =  + 1(delta8/(0 + 1 * delta8))
f_tau_2(delta8) =  + 1(delta8/(0 + 1 * delta8))
g_tau_1(delta5) =  + 1(delta5/(0 + 4 * delta5))
