The set of usable rules consists of

  (no rules)

Take the reduction pair:

  generalized weighted path order (>=MG, >G)
  
    base order 1:
  
      trivial reduction triple (T x T, T x T, Φ)
  
    base order 2:
  
      lexicographic combination of reduction triples:
      
        1. marked-algebra reduction triple (>=A, >=A!, >A!):
        
          matrix interpretation with standard point-wise order:
          
            carrier: N^1
            order: standard order
            interpretations:
              app#_A(x1,x2) = x1
              cons_A(x1,x2) = x1 + x2 + 2
              app#!_A(x1,x2) = x1
              cons!_A(x1,x2) = x2 + 3
        
        2. marked-algebra reduction triple (>=A, >=A!, >A!):
        
          max/plus interpretation on natural numbers:
          
            app#_A(x1,x2) = 0
            cons_A(x1,x2) = max{x1 + 2, x2 - 26}
            app#!_A(x1,x2) = 0
            cons!_A(x1,x2) = 0
        
  
    partial status:
  
      pi(app#) = []
      pi(cons) = [1]

The following rules are removed:

  p1

Then no dependency pair remains.
