試圖用prolog解決這個難題任務,並且遇到了一些問題。prolog在增加堆棧大小時得到語法錯誤
1002 Stack Overflow. Re-configure with Setup if necessary.
所以,我試圖增加安裝程序中的堆棧大小,並再次運行程序。 但它會導致另一個錯誤:Syntax error on line...
錯誤行在謂詞中與運算符「not」一致。
這裏是我的代碼:
domains
age = integer
childname,ffood,fear = string
child = child(childname,age,ffood,fear)
children = child*
predicates
solve
name(child,childname)
fear(child,fear)
age(child,age)
ffood(child,ffood)

solution(children)
elder(child)

structure(children)

structure([child("Dima",_,_,_),child("Kate",_,_,_),child("Misha",_,_,_),child("Sveta",_,_,_),child("Ura",_,_,_)]).

發現了奇怪的這段序言行爲...也許有人有同樣的問題?
感謝ü這麼多! –
