NO Prover = TRS(tech=GUIDED_UNF, nb_unfoldings=unlimited, unfold_variables=true, strategy=LEFTMOST_NE) ** BEGIN proof argument ** The following rule was generated while unfolding the analyzed TRS: [iteration = 1] list1 -> list1 Let l be the left-hand side and r be the right-hand side of this rule. Let p = epsilon, theta1 = {} and theta2 = {}. We have r|p = list1 and theta2(theta1(l)) = theta1(r|p). Hence, the term theta1(l) = list1 loops w.r.t. the analyzed TRS. ** END proof argument ** ** BEGIN proof description ** ## Searching for a generalized rewrite rule (a rule whose right-hand side contains a variable that does not occur in the left-hand side)... No generalized rewrite rule found! ## Searching for a loop by unfolding (unfolding of variable subterms: ON)... # Iteration 0: no loop detected, 19 unfolded rules generated. # Iteration 1: loop detected, 1 unfolded rule generated. Here is the successful unfolding. Let IR be the TRS under analysis. L0 = [list1^# -> hamming^#, hamming^# -> list1^#] is in U_IR^0. We merge the first and the second rule of L0. ==> L1 = list1^# -> list1^# is in U_IR^1. ** END proof description ** Proof stopped at iteration 1 Number of unfolded rules generated by this proof = 20 Number of unfolded rules generated by all the parallel proofs = 20
