The solution using the grandparent relation will not be general enough, try using recursion instead. +Try to transpose the problem into a "smaller" one, e.g. a descendant in one step less (a closer descendant).

How can anyone be a descendant of him- or herself? This can be inferred from the current version of the program. +It might also help to graphically sketch your current solution.

Morda se ti splača preveriti tudi uporabo podpičja. To praktično naredi dva ločena stavka oz. veji -(eno ali drugo velja, morda tudi oboje). Vendar pazi, ker sta ti dve veji med seboj neodvisni --- vrednosti iz ene se ne prenašajo v drugo vejo.

Perhaps you should also check your use of the semicolon. The semicolon basically creates two separate clauses or +branches (one or the other can hold, or even both). However, be careful, as this two branches are independent of +one another -- assigned values to variables in one branch do not transfer to the other branch.

Vse kaže, da tvoj predikat vedno vrne "false". Si mu dal pravilno ime, si se morda pri imenu zatipkal?

Možno je seveda tudi, da so tvoji pogoji prestrogi ali celo nemogoči (kot bi bila npr. zahteva, -da je X hkrati starš in sestra od Y ali kaj podobnega).

Is there an infinite recursion at work here? How will it ever stop?

Or perhaps is there a missing, faulty, or simply incompatible (with the general recursive case) base case?

Interesting tidbit. This exercise could also be solved using the solution to the ancestor/2 +relation. Simply reverse the variables X and Y; +if X is a descendant of Y, then Y is an ancestor of X.
