** BEGIN proof argument **
The following pattern rule was generated by the strategy
presented in Sect. 3 of [Emmes, Enger, Giesl, IJCAR'12]:
[iteration = 1] +(1,_0){}^n{} -> +(1,_0){}^n{}
We apply Theorem 8 of [Emmes, Enger, Giesl, IJCAR'12]
on this rule with m = 1, b = 0, pi = epsilon,
sigma' = {} and mu' = {}.
Hence the term +(1,_0), obtained from
instantiating n with 0 in the left-hand side of
the rule, starts an infinite derivation w.r.t.
the analyzed TRS.

that does not occur in the left-hand side)...
No generalized rewrite rule found!

## Applying the DP framework...
## 1 initial DP problem to solve.
## First, we try to decompose this problem into smaller problems.
## Round 1 [1 DP problem]:
  ## DP problem:
  Dependency pairs = [+^#(1,_0) -> +^#(+(0,1),_0)]
  TRS = {+(1,_0) -> +(+(0,1),_0), +(0,_0) -> _0}
    ## Trying with homeomorphic embeddings... Failed!
    ## Trying with polynomial interpretations... Failed!
    ## Trying with lexicographic path orders... Failed!
    ## Trying with Knuth-Bendix orders... Failed!
  Don't know whether this DP problem is finite.
## A DP problem could not be proved finite.
## Now, we try to prove that this problem is infinite.
    ## Trying to prove non-looping nontermination
      # Iteration 0: non-looping nontermination not proved, 1 unfolded rule generated.
      # Iteration 1: success, non-looping nontermination proved, 1 unfolded rule generated.
      Here is the successful unfolding. Let IR be the TRS under analysis.
      IR contains the dependency pair +^#(1,_0) -> +^#(+(0,1),_0).
      We apply (I) of [Emmes, Enger, Giesl, IJCAR'12] to this dependency pair.
      ==> P0 = +^#(1,_0){}^n{} -> +^#(+(0,1),_0){}^n{} is in U_IR^0.
      We apply (IX) of [Emmes, Enger, Giesl, IJCAR'12] to this pattern rule
      at position [0] using the rule
      +(0,_0) -> _0
      of IR.
      ==> P1 = +^#(1,_0){}^n{} -> +^#(1,_0){}^n{} is in U_IR^1.
  This DP problem is infinite.
