We show the termination of the TRS R:

  *(x,+(y,z)) -> +(*(x,y),*(x,z))

-- SCC decomposition.

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

p1: *#(x,+(y,z)) -> *#(x,y)
p2: *#(x,+(y,z)) -> *#(x,z)

and R consists of:

r1: *(x,+(y,z)) -> +(*(x,y),*(x,z))

The estimated dependency graph contains the following SCCs:

  {p1, p2}


-- Reduction pair.

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

p1: *#(x,+(y,z)) -> *#(x,y)
p2: *#(x,+(y,z)) -> *#(x,z)

and R consists of:

r1: *(x,+(y,z)) -> +(*(x,y),*(x,z))

The set of usable rules consists of

  (no rules)

Take the reduction pair:

  weighted path order
  
    base order:
  
      matrix interpretations:
      
        carrier: N^2
        order: lexicographic order
        interpretations:
          *#_A(x1,x2) = x2 + (1,1)
          +_A(x1,x2) = ((1,0),(0,0)) x1 + x2 + (2,2)
  
    precedence:
    
      *# = +
    
    partial status:
  
      pi(*#) = [2]
      pi(+) = [2]

The next rules are strictly ordered:

  p1

We remove them from the problem.

We remove them from the problem.  Then no dependency pair remains.
