This TRS is terminating using the deltalinear interpretation 
f(delta5, X3) =  + 1*X3 + 0 + 0*X3*delta5 + 0*delta5
mark(delta4, X2) =  + 1*X2 + 0 + 0*X2*delta4 + 3*delta4
a__c(delta3) =  + 0 + 2*delta3
c(delta2) =  + 0 + 0*delta2
g(delta1, X1) =  + 3*X1 + 0 + 1*X1*delta1 + 0*delta1
a__f(delta0, X0) =  + 1*X0 + 0 + 0*X0*delta0 + 1*delta0
f_tau_1(delta5) =  + 1(delta5/(1 + 0 * delta5))
mark_tau_1(delta4) =  + 1(delta4/(1 + 0 * delta4))
g_tau_1(delta1) =  + 1(delta1/(3 + 1 * delta1))
a__f_tau_1(delta0) =  + 1(delta0/(1 + 0 * delta0))
