PCB Question Tree

While(hasQuestions){Answers.Add(getUserAnswer());if(a == null) break; //user pressed “done”Question newQuestion = getNextQuestion(a);showQuestion(newQuestion);

}

PCB Engine Input

x The algorithm will get as input the user answers and a sorted list of components.

x The list of components will be sorted by their relevance to the user’s answers.

PCB Engine (Algorithm)

While(totalMoney < budget){f1.addComponent(sortedComponents, budget);

}f2 = replaceLessSeg(sortedComponents, budget);undo(f1);

While(moreCompToReplace){moreCompToReplace = replaceNextComponent(f1);

}finalProduct = compare(f1, f2);
