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.

## 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 = [f^#(_0,c(_0)) -> f^#(s(_0),_0)]
  TRS = {f(s(_0),_0) -> f(_0,a(_0)), f(_0,c(_0)) -> f(s(_0),_0), f(_0,_0) -> c(_0)}
    ## Trying with homeomorphic embeddings... Failed!
    ## Trying with polynomial interpretations...
      The constraints are satisfied by the polynomials:
      {f(_0,_1):[_0 * _1], a(_0):[_0], c(_0):[2 * _0], s(_0):[_0], f^#(_0,_1):[_0 * _1]}
      for all instantiations of the variables with values greater than or equal to mu = 2.
  This DP problem is finite.
