Decision Procedures

Decision Procedures are the basis for program verification: The task of program verification is to give a formal proof that a program meets its specification. This amounts to determining the truth value of a logical formula. A decision procedure is an algorithm that can for a certain type of formulas decide whether the formula is true or false. We will investigate decision procedures for different logics. Starting with propositional logic we will investigate decision procedures for logics with integers, reals, recursive structures (lists and trees), arrays, etc.

Admission criteria

Half of the maximum points from the exercises have to be achieved in order to be admitted for the exam. There will be an exercise sheet each week, usually with three exercises and a maximum of 12 points. You can usually hand in your submission before the lecture on Tuesday -- alone or in groups of two.

Exam

The exam will be oral or written, depending on the number of participants.

 Please register via the examination office as usual.
