私はプロローグを新しくしており、この課題を完了する必要があります。 私は、私が持っている事実と私が自分で作った結論との関係を作る方法について非常に混乱しています。 この質問のコードセクションには、特定の情報のリストとデータからの私の結論が掲載されています。 割り当てを完了するために正しい方向に導くことができれば、私はそれを感謝するでしょう。 ありがとうございます!元の質問TOProlog Jobs Puzzle
%There are three people: John, Jim, and Mary and each has two jobs.
%The jobs are gardener, veterinarian's assistant, dishwasher, nurse,
%high school math teacher, and biology tutor.
%You are given the following information:
%1) The nurse went out with the veterinarian's assistant last night.
%2) Mary is friends with the biology tutor but she stayed home last night.
%3) Jim likes animals but he failed math and had to drop out of college.
%4) Jim does not know the gardener.
%5) Mary and the biology tutor used to be married.
%My Conclusions from Facts:
%6) Mary is not the biologyTutor because she did not go out with the
% biologyTutor and she was married to the biology tutor (2&5)
%7) Jim is not the highSchoolMathTeacher because he failed math (3)
%8) Jim is not the gardener because he does not know the gardener (4)
%9) Mary is not the nurse/vetAssistant because she did not go out (1&2)
%10) The biologyTutor went out last night (1&2)
%Who holds which jobs? Include a report explaining your strategy.
%Exepcted Answers:
%Mary: gardener, highSchoolMathTeacher
%Jim: vetAssistant, dishWasher
%John: nurse, biologyTutor
%Given Information, aka FACTS:
%person(Name).
person(mary).
person(jim).
person(john).
%job(JobName).
job(gardener).
job(vetAssistant).

%list of jobs

%length of variables are 2 &
%Solution is person and corresponding variables
length(MaryJobs,2),
length(JimJobs,2),
length(JohnJobs,2),
Solution = [mary-MaryJobs,jim-JimJobs,john-JohnJobs],
%query to find the jobs AllJobs is a list containing variables of the jobs
findAll(Jobs,job(Job),AllJobs),
AllJobs = [Gardener,VetAssistant,DishWasher,Nurse,MathTeacher,BioTutor],
%Note: im not sure about flatten
flatten([MaryJobs,JimJobs,JohnJobs],Jobs),
permutation(Jobs,AllJobs),
% 6 & 9; Mary is not the Nurse, VetAssistant, or BioTutor
\+ member(Nurse,MaryJobs),
\+ member(VetAssistant,MaryJobs),
\+ member(BioTutor, MaryJobs),
% 7 & 8 & 3 ; Jim is not the MathTeacher or Gardener
\+ member(MathTeacher,JimJobs),
\+ member(Gardener, JimJobs),
%Mary is the Gardener because Jim does not know the
%Gardener, therefore he cannot have gone out with the Gardener.
\+ member(Gardener, JohnJobs),
%Jim must not KNOW Mary because she is the Gardener
%John and Mary must have been married
%Conclusion: Jim is not the Bio Tutor
\+ member(BioTutor, JimJobs),
%logically, since Jim likes animals, it would make sense if he
%were the VetAssistant and since this is true, John is the nurse
\+ member(VetAssistant, JohnJobs),
\+ member(Nurse, JimJobs),
%logically since jim dropped out of college, it would make sense
%if he were to be the dishwasher
\+ member(DishWasher, MaryJobs),
\+ member(DishWasher, JohnJobs).
%Automatically this is should conclude that Mary is the MathTeacher
を、私はエラーが発生します。
length(MaryJobs,2),

Solution = [mary-MaryJobs,jim-JimJobs,john-JohnJobs],
私が受けていますエラーメッセージは次のとおりです:

あなたの割り当ての最終的な陳述は非常に明白です。あなたの戦略を説明する必要があります**。だから、可能な**計算可能な**解決策であると思われるものについてのヒントを教えてください。 – CapelliC
すべてのコードを関連する述語に入れる必要があります。だから、 'length(MaryJobs、..)'で始めるところで、 'solve(Solution): - length(...)'のような述語名を挿入します。第二に、あなたの 'findall'ステートメントでは' Job'と 'Jobs'があります - したがって、シングルトンの警告は同じ名前に変更してみてください。 – SND
