1.1 Semantic Labeling

As carrier we take the set {0,1,2}. Symbols are labeled by the interpretation of their arguments using the interpretations (modulo 3):

1.1.1 Rule Removal

1.1.1.1 Dependency Pair Transformation

1.1.1.1.1 Monotonic Reduction Pair Processor with Usable Rules

1.1.1.1.1.1 Dependency Graph Processor

The dependency pairs are split into 4 components.

• The 1^st component contains the pair

  c1#(b1(x1))

  →

  c1#(x1)

  (53)

  1.1.1.1.1.1.1 Monotonic Reduction Pair Processor with Usable Rules

  Using the matrix interpretations of dimension 1 with strict dimension 1 over the rationals with delta = 1

  [b1(x1)]	=	x1 + 1
  [c1#(x1)]	=	x1 + 0

  having no usable rules (w.r.t. the implicit argument filter of the reduction pair), the pair

  c1#(b1(x1))

  →

  c1#(x1)

  (53)

  and no rules could be deleted.

  1.1.1.1.1.1.1.1 Dependency Graph Processor

  The dependency pairs are split into 0 components.

• The 2^nd component contains the pair

  c2#(a2(x1))

  →

  c2#(x1)

  (72)

  1.1.1.1.1.1.2 Monotonic Reduction Pair Processor with Usable Rules

  Using the matrix interpretations of dimension 1 with strict dimension 1 over the rationals with delta = 1

  [a2(x1)]	=	x1 + 1
  [c2#(x1)]	=	x1 + 0

  having no usable rules (w.r.t. the implicit argument filter of the reduction pair), the pair

  c2#(a2(x1))

  →

  c2#(x1)

  (72)

  and no rules could be deleted.

  1.1.1.1.1.1.2.1 Dependency Graph Processor

  The dependency pairs are split into 0 components.

• The 3^rd component contains the pair

  b2#(a2(x1))

  →

  b2#(x1)

  (90)

  1.1.1.1.1.1.3 Monotonic Reduction Pair Processor with Usable Rules

  Using the matrix interpretations of dimension 1 with strict dimension 1 over the rationals with delta = 1

  [a2(x1)]	=	x1 + 1
  [b2#(x1)]	=	x1 + 0

  having no usable rules (w.r.t. the implicit argument filter of the reduction pair), the pair

  b2#(a2(x1))

  →

  b2#(x1)

  (90)

  and no rules could be deleted.

  1.1.1.1.1.1.3.1 Dependency Graph Processor

  The dependency pairs are split into 0 components.

• The 4^th component contains the pair

  a1#(b1(x1))

  →

  a1#(x1)

  (92)

  1.1.1.1.1.1.4 Monotonic Reduction Pair Processor with Usable Rules

  Using the matrix interpretations of dimension 1 with strict dimension 1 over the rationals with delta = 1

  [b1(x1)]	=	x1 + 1
  [a1#(x1)]	=	x1 + 0

  having no usable rules (w.r.t. the implicit argument filter of the reduction pair), the pair

  a1#(b1(x1))

  →

  a1#(x1)

  (92)

  and no rules could be deleted.

  1.1.1.1.1.1.4.1 Dependency Graph Processor

  The dependency pairs are split into 0 components.
