NWI-IPK001: Introduction to Formal Reasoning

So this page is not for SOW-BKI146: Formal Reasoning for AI!

Teachers

Two versions of Formal Reasoning

As of September 2025, AI students will follow their own 'Formal Reasoning for AI' course with code SOW-BKI146. Although the first half of the courses SOW-BKI146 and NWI-IPK001 coincide, the two courses are officially different courses, with their own rules. As this is the page for NWI-IPK001 the course information on this page does not apply to SOW-BKI146 as well. In particular, the SOW-BKI146 course has different rules for passing the course, so if you are doing the AI version, please check the Brightspace site for SOW-BKI146!

Course material

The course notes will become available as a PDF on this page. The chapters are:

There are four intermediate tests. The first one is about Chapters 1 and 2, the second about Chapter 3, the third about Chapter 4, and the fourth about Chapters 5 and 6. These tests will be done digitally using the ANS digital assessment software. These tests are currently scheduled to be on-campus only. The tests contain both 'closed questions' as well as 'open questions'. These tests are not obligatory because there is a final exam at the end of the semester. However, these intermediate tests can be used to improve the result of the final exam using the formula described below on this page.

Late registration

For students who want to register for this course, but cannot do this anymore because the registration is closed in Osiris: please contact the Student Service Desk (STIP) at the Science faculty.

Schedule

On this page we try to list as clearly as possible what will be done at which moment in time within this course. However, this page is manually maintained, hence for instance changes of lecture halls are not automatically processed. Therefore, you should always check your personal schedule for the latest information on rooms and exam dates.

The coordinates of this course are:

On some days we do not follow the normal schedule of a plenary lecture followed by an exercise hour. You can see this in the schedule below. The colors indicate the type of activity. In particular this is the case when we have an intermediate test. These intermediate tests always take place from 18.00--18.45, which is the time implied by the digital exam organization. Each of these tests is preceded by a response lecture where you can ask questions and are expected to answer other people's questions about the topic of the test. These response lectures will be in the second hour of a lecture block, so both on Monday and on Thursday at 16.30--17.15.

Grading

The final grade is calculated via the formula

max(exam, (average of four intermediate tests + exam)/2)

Final grades are rounded into halves. However, since we are not allowed to register a 5.5 within Osiris, grades between 5.5 (inclusive) and 6.0 will be rounded upwards to a 6.0 and grades between 5.0 and 5.5 (exclusive) will be rounded downwards to a 5.0.

Both the tests and the exam are "closed book". The additional test in January is intended for students who missed one or more of the other tests, but other students may try it as well. Note that this single test covers all topics. So if you missed the test on propositional and predicate logic you will also have to study all other topics for the additional test (which is of course a good preparation for the final exam).

Resources and solutions

The file containing the solutions will normally be updated twice a week with the solutions of last lecture's exercises. However, since this is a manual process, we might forget it. In addition, the solutions will also become available via a second channel in Brightspace, so if we forgot to update the file on this page, you might check the course content within Brightspace.

Tests and exams

Below you can find a long list of intermediate tests and exams from this year and previous years. Unfortunately, all tests before 2016--2017 were in Dutch. In order to provide more options for studying the course material for those who do not speak Dutch, we translated some old tests to English. If the text below is in Dutch then the test and solutions are also in Dutch. In addition, be aware that we only started using digital tests in the year 2020--2021, so the older tests may be somewhat different.
