The last lecture took place on July 3. On July 10 at 10:15, there will be the last
exercise course (for V3M).

In addition to a short introduction to the programming language Prolog, the
lecture deals with the foundations of logic programming, with programming
techniques in these languages, with the implementation of logic
programming languages, and with their application in several areas.
More precisely, these are the topics of the lecture:
- Prerequisites from predicate logic
- Horn clauses and SLD-resolution
- Operational and denotational semantics
- Evaluation strategies
The programming language Prolog
- Syntax and semantics
- Negation as failure
- Non-logical components of Prolog
- Programming techniques
- Applications and extensions of logic programming
Versions of the Lecture
Not all material of the lecture is needed for all students. More precisely, there are two versions of the lecture:
- V3B This version consists of a subset of the full lecture (with 3 hours per week). It
is relevant for students in Bachelor Informatik, Master Mathematik, and Master TK.
The following material is missing
- Section 4.2 (universality of logic programming)
- Section 6 (constraint logic programming)
- V3M This version also consists of a subset of the full lecture (with 3 hours per week). It
is relevant for students in Master Informatik and Master SSE. This is also the version that is relevant for those students in Bachelor Informatik who already want to attend the master-version of this course (they can transfer the credits obtained here as soon as they enter the master program).
The following material is missing
- Section 5.5 (input and output)
- Section 5.6 (meta programming)
- Section 5.7 (difference lists and definite clause grammars)

To write Prolog-programs, we recommend the SWI Prolog System.
An alternative to SWI-Prolog is GNU
The exercises have to be solved in groups of two or three.
50% of the points on the exercise sheets are
needed in order to take part in the final written exam. The written exam will be on
August 19, 2015. If you fail this exam, there will be a second written exam on
September 14, 2015. There will not be any extra oral exams, i.e., you need to take part in
the written exams in August or September 2015.
In order to take part in the exercises, please sign
up here until Friday, April 17.

substitution is computed as follows. Consider an SLD resolution proof from a
negative clause N of the
form N, R1, R2, ..., Rm,
where Rm is the empty clause □. So R1
is the resolvent of N and a definite clause from the input set. Similarly, R2 is the
resolvent of R1 and a definite clause from the input set, etc. Moreover, assume that
no variable renamings have been applied
to N, R1, R2, ..., Rm.
first resolution step, let σ1 be the used mgu. In the second resolution step, one
used the mgu σ2, etc. Then the answer substitution is σm ○ ... ○
σ2 ○ σ1, i.e., σ1 is applied first in this composition of
substitutions. Moreover, the answer substitution is restricted to those variables that
occur in the original negative clause N.

Here you find exams from the 2006, 2008, 2010, and 2013 lectures on logic
programming (partially in German).
However, as the computer science curriculum has been changed after
the 2008 lecture took place, the conditions for the 2006 and 2008 exams were different from
the ones since 2010. First, the old exams were not
designed to determine the final grade for the logic programming course, but only for the
acquisition of the Übungsschein. Second, they only took 90 minutes, while the exams since
2010 take 120 minutes. Third, we will have two different exams
(according to the two versions of the lecture) instead of just one in 2006 and 2008 or
three in 2010. Keep these differences in mind when practising with the old
exams. Furthermore, we strongly recommend that you solve the old exams without looking
into the solutions first and that you also respect the time limit
(90 minutes for the exams of 2006 and 2008, 120 minutes for the exams of 2010 and 2013).
