Problem:
 cond1(true(),x,y) -> cond2(gr(x,y),x,y)
 cond2(true(),x,y) -> cond3(gr(x,0()),x,y)
 cond2(false(),x,y) -> cond4(gr(y,0()),x,y)
 cond3(true(),x,y) -> cond3(gr(x,0()),p(x),y)
 cond3(false(),x,y) -> cond1(and(gr(x,0()),gr(y,0())),x,y)
 cond4(true(),x,y) -> cond4(gr(y,0()),x,p(y))
 cond4(false(),x,y) -> cond1(and(gr(x,0()),gr(y,0())),x,y)
 gr(0(),x) -> false()
 gr(s(x),0()) -> true()
 gr(s(x),s(y)) -> gr(x,y)
 and(true(),true()) -> true()
 and(false(),x) -> false()
 and(x,false()) -> false()
 p(0()) -> 0()
 p(s(x)) -> x
