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] app(app(app(fix,subst),_0),_1) -> app(app(app(fix,subst),_1),app(_0,_1)) Let l be the left-hand side and r be the right-hand side of this rule. Let p = epsilon, theta1 = {} and theta2 = {_1->app(_0,_1), _0->_1}. We have r|p = app(app(app(fix,subst),_1),app(_0,_1)) and theta2(theta1(l)) = theta1(r|p). Hence, the term theta1(l) = app(app(app(fix,subst),_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, 3 unfolded rules generated. # Iteration 1: loop detected, 15 unfolded rules generated. Here is the successful unfolding. Let IR be the TRS under analysis. L0 = app^#(app(app(subst,_0),_1),_2) -> app^#(app(_0,_2),app(_1,_2)) is in U_IR^0. Let p0 = [0]. We unfold the rule of L0 backwards at position p0 with the rule app(app(fix,_0),_1) -> app(app(_0,app(fix,_0)),_1). ==> L1 = app^#(app(app(fix,subst),_0),_1) -> app^#(app(app(fix,subst),_1),app(_0,_1)) is in U_IR^1. ** END proof description ** Proof stopped at iteration 1 Number of unfolded rules generated by this proof = 18 Number of unfolded rules generated by all the parallel proofs = 18 popout
