YES

This TRS is terminating using the restricteddeltasimple interpretation 
s(delta9) =  + 1 + 0*delta9
0(delta8) =  + 1 + 0*delta8
plus(delta7) =  + 0 + 1*delta7
id(delta6) =  + 1 + 0*delta6
app(delta5, X3, X2) =  + 1*X2 + 1*X3 + 0 + 0*X2*delta5 + 1*X3*delta5 + 0*delta5
app_tau_1(delta5) =  + 1(delta5/(1 + 1 * delta5))
app_tau_2(delta5) =  + 1(delta5/(1 + 0 * delta5))
