* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          +(x,#()) -> x
          +(#(),x) -> x
          +(+(x,y),z) -> +(x,+(y,z))
          +(0(x),0(y)) -> 0(+(x,y))
          +(0(x),1(y)) -> 1(+(x,y))
          +(1(x),0(y)) -> 1(+(x,y))
          +(1(x),1(y)) -> 0(+(+(x,y),1(#())))
          -(x,#()) -> x
          -(#(),x) -> #()
          -(0(x),0(y)) -> 0(-(x,y))
          -(0(x),1(y)) -> 1(-(-(x,y),1(#())))
          -(1(x),0(y)) -> 1(-(x,y))
          -(1(x),1(y)) -> 0(-(x,y))
          0(#()) -> #()
          ge(x,#()) -> true()
          ge(#(),0(x)) -> ge(#(),x)
          ge(#(),1(x)) -> false()
          ge(0(x),0(y)) -> ge(x,y)
          ge(0(x),1(y)) -> not(ge(y,x))
          ge(1(x),0(y)) -> ge(x,y)
          ge(1(x),1(y)) -> ge(x,y)
          if(false(),x,y) -> y
          if(true(),x,y) -> x
          log(x) -> -(log'(x),1(#()))
          log'(#()) -> #()
          log'(0(x)) -> if(ge(x,1(#())),+(log'(x),1(#())),#())
          log'(1(x)) -> +(log'(x),1(#()))
          not(false()) -> true()
          not(true()) -> false()
      - Signature:
          {+/2,-/2,0/1,ge/2,if/3,log/1,log'/1,not/1} / {#/0,1/1,false/0,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {+,-,0,ge,if,log,log',not} and constructors {#,1,false
          ,true}
  + Applied Processor:
      EmptyProcessor
  + Details:
      The problem is still open.
