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 = 2] f(g(0,_0),1,g(0,_0)) -> f(g(0,_0),_0,g(0,_0)) Let l be the left-hand side and r be the right-hand side of this rule. Let p = epsilon, theta1 = {_0->1} and theta2 = {}. We have r|p = f(g(0,_0),_0,g(0,_0)) and theta2(theta1(l)) = theta1(r|p). Hence, the term theta1(l) = f(g(0,1),1,g(0,1)) 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, 1 unfolded rule generated. # Iteration 1: no loop detected, 4 unfolded rules generated. # Iteration 2: loop detected, 8 unfolded rules generated. Here is the successful unfolding. Let IR be the TRS under analysis. L0 = f^#(0,1,_0) -> f^#(_0,_0,_0) is in U_IR^0. Let p0 = [0]. We unfold the rule of L0 backwards at position p0 with the rule g(_0,_1) -> _0. ==> L1 = f^#(g(0,_0),1,g(0,_0)) -> f^#(g(0,_0),g(0,_0),g(0,_0)) is in U_IR^1. Let p1 = [1]. We unfold the rule of L1 forwards at position p1 with the rule g(_0,_1) -> _1. ==> L2 = f^#(g(0,1),1,g(0,1)) -> f^#(g(0,1),1,g(0,1)) is in U_IR^2. ** END proof description ** Proof stopped at iteration 2 Number of unfolded rules generated by this proof = 13 Number of unfolded rules generated by all the parallel proofs = 14
