This TRS is terminating using the deltarestricted interpretation 
minux(delta2, X3) =  + 1*X3 + 0 + 0*X3*delta2 + 3*delta2
+(delta1, X2, X1) =  + 1*X1 + 1*X2 + 0 + 0*X1*delta1 + 0*X2*delta1 + 0*delta1
minus(delta0, X0) =  + 1*X0 + 0 + 0*X0*delta0 + 1*delta0
minux_tau_1(delta2) =  + 1(delta2/(1 + 0 * delta2))
+_tau_1(delta1) =  + 1(delta1/(1 + 0 * delta1))
+_tau_2(delta1) =  + 1(delta1/(1 + 0 * delta1))
minus_tau_1(delta0) =  + 1(delta0/(1 + 0 * delta0))
