Self Assessment Questionnaires

 

These questionnaires are to be read during your revision, to check (and perhaps improve) your understanding.

They have the form of a question and a number of options but they are NOT really multiple choice questions, since sometimes more than once answer will be correct, sometime answers are debatable, and sometime all the options need a response. This is different from the second class test and the exam will use proper multiple choice questions: in the test and the exam each question will have five options, one (and only one) of which is right.

Some of the questions may go beyond what I have presented in lectures. The exam, however, will be on what I have presented in lectures.

 

The Questionnaires cover a number of topics:

 

Logic and Search

Production Rules

Structured Objects

Logic Programming

Note in this questionnaire resolution is used on sentences in Clausal Normal Form. Clausal Normal Form is Head IF Body, where Head is Disjunction of positive literals and Body is a  Conjunction of positive literals. No negative literals occur. Two clauses have a complementary literal if a literal occurs in the head of one clause and the body of the other. The resolvent is the disjunction of the remaining literals in the heads of both clauses IF the conjunction of the remaining literals in both clauses. This is simply a syntactic variant on resolution in CNF, which is closer to Prolog.
