The content of each lecture and excersise session, or the deadline for assignments will be updated during the running of the course to take possible deviations into account. See link at Time Edit for the up-to-date schedule during VT Terminology: Lec: Lectures. Ex: Exercise classes. The tutor will work on the blackboard on a predefined set of exercises. Students are encourage to try the exercises prior to the class in order to take the most out of it. There will be two instances for the same exercise class; you can choose the one that suits you best.
That string is not in L, so we contradict the assumption that L is regular.

In the USA of the 's it became popular to teach proof as a matter of personal feelings about the statement. While it is good to feel the truth of a statement you need to use, important techniques of proof are no longer mastered in high school. Yet proof is something that every computer scientist needs to understand. Some computer scientists take the extreme view that a formal proof of the correctness of a program should go hand-in-hand with the writing of the program itself.
We doubt that doing so is productive. On the other hand, there are those who say that proof has no place in the discipline of programming.
Our position is between these two extremes. Testing programs is surely essential.
However, testing goes only so far, since you cannot try your program on every input. When your testing tells you the code is incorrect, you still need to get it right. To make your iteration or recursion correct, you need to set up an inductive hypothesis, and it is helpful to reason, formally or informally, that the hypothesis is consistent with the iteration or recursion.
This process of understanding the workings of a correct program is essentially the same as the process of proving theorems by induction. Thus, in addition to giving you models that are useful for certain types of software, it has become traditional for a course on automata theory to cover methodologies of formal proof.
Each step in the proof must follow, by some accepted logical principle, from either the given facts, or some of the previous statements in the deductive proof, or a combination of these.
This nickname is derived from a girl putatively Cinderella on the cover with a Rube Goldberg machine. Edition history and reception[ edit ] The forerunner of this book appeared under the title Formal Languages and Their Relation to Automata in Forming a basis both for the creation of courses on the topic, as well as for further research, that book shaped the field of automata theory for over a decade, cf.
