252-4230-00L | Advanced Algorithms and Data Structures Number of participants limited to 24. As a prerequisite, students must have more than just basic knowledge on algorithms and data structures. If you have enjoyed the class "Algorithms, Probability and Computing", this seminar is just right for you! The deadline for deregistering expires at the end of the second week of the semester. Students who are still registered after that date, but do not attend the seminar, will officially fail the seminar. Takes place for the last time! | 2 credits | 2S | P. Widmayer, S. Leucci, P. Uznanski | |

Abstract | We will look into modern approaches of algorithms and data structures. A few breakthrough and highly influential papers from the general area of algorithms, from the past 20 years will be selected for students to study. | ||||

Objective | Develop an understanding of modern techniques and paradigms in the design of algorithms and data structures. | ||||

Content | Topics include (but are not exhausted by): -graph algorithms, -text algorithms, -approximation algorithms, -algebra in algorithms, -streaming algorithms, -conditional lower bounds, -sparsification, -randomness in algorithms, -sampling. | ||||

Prerequisites / Notice | Algorithms and Data Structures, or equivalent. | ||||

263-0006-00L | Algorithms LabOnly for master students, otherwise a special permission by the student administration of D-INFK is required. | 8 credits | 4P + 3A | A. Steger, E. Welzl, P. Widmayer | |

Abstract | Students learn how to solve algorithmic problems given by a textual description (understanding problem setting, finding appropriate modeling, choosing suitable algorithms, and implementing them). Knowledge of basic algorithms and data structures is assumed; more advanced material and usage of standard libraries for combinatorial algorithms are introduced in tutorials. | ||||

Objective | The objective of this course is to learn how to solve algorithmic problems given by a textual description. This includes appropriate problem modeling, choice of suitable (combinatorial) algorithms, and implementing them (using C/C++, STL, CGAL, and BGL). | ||||
