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