This TRS is terminating using the restricteddeltasimple interpretation 
g(delta7, X7) =  + 0*X7 + 0 + 1*X7*delta7 + 0*delta7
b(delta6, X6) =  + 0*X6 + 0 + 1*X6*delta6 + 2*delta6
a(delta5, X5) =  + 0*X5 + 0 + 1*X5*delta5 + 0*delta5
f(delta4, X4) =  + 0*X4 + 3 + 2*X4*delta4 + 3*delta4
g_tau_1(delta7) =  + 1(delta7/(0 + 1 * delta7))
b_tau_1(delta6) =  + 1(delta6/(0 + 1 * delta6))
a_tau_1(delta5) =  + 1(delta5/(0 + 1 * delta5))
f_tau_1(delta4) =  + 1(delta4/(0 + 2 * delta4))
