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!):
        
          max/plus interpretation on natural numbers:
          
            plus_2#_A(x1,x2) = max{0, x1 - 5}
            s_1_A(x1) = max{12, x1 + 4}
            |app'|_A(x1,x2) = max{1, x1 - 133, x2 - 96}
            filter2_2_A(x1,x2) = max{2, x1 - 1, x2 - 1}
            filter2_3_A(x1,x2,x3) = max{1, x1 - 134, x2 - 134, x3 - 96}

            filter2_3!_A(x1,x2,x3) = max{106, x3 - 2}
        
        2. marked-algebra reduction triple (>=A, >=A!, >A!):
        
          matrix interpretation with standard point-wise order:
          
            carrier: N^1
            order: standard order
            interpretations:
              plus_2#_A(x1,x2) = x1
              s_1_A(x1) = x1 + 6
              |app'|_A(x1,x2) = x1 + x2 + 1

              plus_2#!_A(x1,x2) = x1
              s_1!_A(x1) = x1 + 22
              |app'|!_A(x1,x2) = 21
              filter2_2!_A(x1,x2) = 2
              filter2_3!_A(x1,x2,x3) = 1
        
  
    partial status:
  
      pi(plus_2#) = []
      pi(s_1) = [1]
      pi(|app'|) = [1, 2]
      pi(filter2_2) = []
      pi(filter2_3) = []

The following rules are removed:

  p1

Then no dependency pair remains.
