* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          lcs(x,e()) -> 0()
          lcs(a(x),a(y)) -> s(lcs(x,y))
          lcs(a(x),b(y)) -> max(lcs(x,b(y)),lcs(a(x),y))
          lcs(b(x),a(y)) -> max(lcs(x,a(y)),lcs(b(x),y))
          lcs(b(x),b(y)) -> s(lcs(x,y))
          lcs(e(),y) -> 0()
          max(x,0()) -> 0()
          max(0(),y) -> 0()
          max(s(x),s(y)) -> max(x,y)
      - Signature:
          {lcs/2,max/2} / {0/0,a/1,b/1,e/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {lcs,max} and constructors {0,a,b,e,s}
  + Applied Processor:
      EmptyProcessor
  + Details:
      The problem is still open.
