This TRS is terminating using the restricteddeltasimple interpretation 
g(delta7, X9) =  + 0*X9 + 0 + 1*X9*delta7 + 0*delta7
s(delta6, X8) =  + 1*X8 + 1 + 0*X8*delta6 + 0*delta6
c(delta5, X7, X6) =  + 0*X6 + 1*X7 + 0 + 2*X6*delta5 + 0*X7*delta5 + 0*delta5
f(delta4, X5) =  + 0*X5 + 0 + 3*X5*delta4 + 0*delta4
g_tau_1(delta7) =  + 1(delta7/(0 + 1 * delta7))
s_tau_1(delta6) =  + 1(delta6/(1 + 0 * delta6))
c_tau_1(delta5) =  + 1(delta5/(1 + 0 * delta5))
c_tau_2(delta5) =  + 1(delta5/(0 + 2 * delta5))
