YES

This TRS is terminating using the restricteddeltasimple interpretation 
0(delta7) =  + 0 + 0*delta7
g(delta6, X5) =  + 0*X5 + 0 + 3*X5*delta6 + 0*delta6
s(delta5, X4) =  + 0*X4 + 3 + 2*X4*delta5 + 0*delta5
f(delta4, X3) =  + 0*X3 + 0 + 2*X3*delta4 + 1*delta4
g_tau_1(delta6) =  + 1(delta6/(0 + 3 * delta6))
s_tau_1(delta5) =  + 1(delta5/(0 + 2 * delta5))
f_tau_1(delta4) =  + 1(delta4/(0 + 2 * delta4))
