Prover = TRS(tech=GUIDED_UNF_TRIPLES, nb_unfoldings=unlimited, unfold_variables=false, max_nb_coefficients=12, max_nb_unfolded_rules=-1, strategy=LEFTMOST_NE)

** BEGIN proof argument **
All the DP problems were proved finite.
As all the involved DP processors are sound,
the TRS under analysis terminates.
** 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!

## Applying the DP framework...
## Round 1:
  ## DP problem: 
  Dependency pairs = [++^#(.(_0,_1),_2) -> ++^#(_1,_2), ++^#(++(_0,_1),_2) -> ++^#(_0,++(_1,_2)), ++^#(++(_0,_1),_2) -> ++^#(_1,_2)]
  TRS = {++(nil,_0) -> _0, ++(_0,nil) -> _0, ++(.(_0,_1),_2) -> .(_0,++(_1,_2)), ++(++(_0,_1),_2) -> ++(_0,++(_1,_2))}
    ## Trying with homeomorphic embeddings... Failed!
    ## Trying with polynomial interpretations...
      The constraints are satisfied by the polynomials:
      {++(_0,_1):[_0 * _1], .(_0,_1):[_0 * _1], nil:[2], ++^#(_0,_1):[_0]}
      for all instantiations of the variables with values greater than or equal to mu = 2.
  This DP problem is finite.
