Problem:
 b(w(x)) -> w(w(w(b(x))))
 w(b(x)) -> b(x)
 b(b(x)) -> w(w(w(w(x))))
 w(w(x)) -> w(x)

Proof:
 Church Rosser Transformation Processor (kb):
  b(w(x)) -> w(w(w(b(x))))
  w(b(x)) -> b(x)
  b(b(x)) -> w(w(w(w(x))))
  w(w(x)) -> w(x)
  critical peaks: joinable
  Matrix Interpretation Processor: dim=1
   
   interpretation:
    [b](x0) = 5x0 + 3,
    
    [w](x0) = x0 + 4
   orientation:
    b(w(x)) = 5x + 23 >= 5x + 15 = w(w(w(b(x))))
    
    w(b(x)) = 5x + 7 >= 5x + 3 = b(x)
    
    b(b(x)) = 25x + 18 >= x + 16 = w(w(w(w(x))))
    
    w(w(x)) = x + 8 >= x + 4 = w(x)
