This TRS is terminating using the restricteddeltasimple interpretation 
++(delta7, X5, X4) =  + 1*X4 + 1*X5 + 1 + 0*X4*delta7 + 0*X5*delta7 + 0*delta7
b(delta6) =  + 1 + 0*delta6
rev(delta5, X3) =  + 1*X3 + 0 + 1*X3*delta5 + 0*delta5
a(delta4) =  + 1 + 0*delta4
++_tau_1(delta7) =  + 1(delta7/(1 + 0 * delta7))
++_tau_2(delta7) =  + 1(delta7/(1 + 0 * delta7))
rev_tau_1(delta5) =  + 1(delta5/(1 + 1 * delta5))
