We show the termination of the TRS R:

  times(x,|0|()) -> |0|()
  times(x,s(y)) -> plus(times(x,y),x)
  plus(x,|0|()) -> x
  plus(|0|(),x) -> x
  plus(x,s(y)) -> s(plus(x,y))
  plus(s(x),y) -> s(plus(x,y))


-- SCC decomposition.

Consider the dependency pair problem (P, R), where P consists of

p1: times#(x,s(y)) -> plus#(times(x,y),x)
p2: times#(x,s(y)) -> times#(x,y)
p3: plus#(x,s(y)) -> plus#(x,y)
p4: plus#(s(x),y) -> plus#(x,y)

and R consists of:

r1: times(x,|0|()) -> |0|()
r2: times(x,s(y)) -> plus(times(x,y),x)
r3: plus(x,|0|()) -> x
r4: plus(|0|(),x) -> x
r5: plus(x,s(y)) -> s(plus(x,y))
r6: plus(s(x),y) -> s(plus(x,y))

The estimated dependency graph contains the following SCCs:

  {p2}
  {p3, p4}

Take the reduction pair:

  generalized weighted path order (>=MG, >MG)
  
    base order 1:
  
      matrix interpretation with standard point-wise order:
      
        carrier: N^1
        order: standard order
        interpretations:
          times#_A(x1,x2) = x2
          s_A(x1) = x1 + 3
          plus_A(x1,x2) = x2
          |0|_A() = 1

      pi(times#) = [2]
      pi(s) = []
      pi(plus) = [2]
      pi(|0|) = []

The following rules are removed:

Then no dependency pair remains.
