* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          eq(0(),0()) -> true()
          eq(0(),s(x)) -> false()
          eq(s(x),0()) -> false()
          eq(s(x),s(y)) -> eq(x,y)
          if_reach_1(false(),x,y,edge(u,v,i),h) -> reach(x,y,i,edge(u,v,h))
          if_reach_1(true(),x,y,edge(u,v,i),h) -> if_reach_2(eq(y,v),x,y,edge(u,v,i),h)
          if_reach_2(false(),x,y,edge(u,v,i),h) -> or(reach(x,y,i,h),reach(v,y,union(i,h),empty()))
          if_reach_2(true(),x,y,edge(u,v,i),h) -> true()
          or(false(),y) -> y
          or(true(),y) -> true()
          reach(x,y,edge(u,v,i),h) -> if_reach_1(eq(x,u),x,y,edge(u,v,i),h)
          reach(x,y,empty(),h) -> false()
          union(edge(x,y,i),h) -> edge(x,y,union(i,h))
          union(empty(),h) -> h
      - Signature:
          {eq/2,if_reach_1/5,if_reach_2/5,or/2,reach/4,union/2} / {0/0,edge/3,empty/0,false/0,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {eq,if_reach_1,if_reach_2,or,reach
          ,union} and constructors {0,edge,empty,false,s,true}
