The Swiss engineering master's degree

This module introduces students with different categories of advanced algorithms and typical application areas.
In the first part of the module, the students will have a sound understanding of data structures and algorithms for efficiently handling either very large, complex or dynamic data sets or combinations thereof. They will be able to evaluate suitable algorithms and to apply them to typical tasks such as efficiently indexing, searching, retrieving, inserting or updating data such as large volumes of hypertext or spatial data.
The students will be familiar with dynamic algorithms used, for example, in artificial intelligence.
The second part of the module will present basic techniques for designing algorithms for hard combinatorial optimization problems. The combination of these basic components —problem modeling, problem decomposition, solution building, solution improvement, learning— lead to classical metaheuristics like genetic algorithms, ant colonies or tabu search. The students will be able to design new algorithms for hard combinatorial optimization problems and to apply them.

Requisiti

The student has working knowledge of:

• Geometry, linear algebra, algorithms (sorting, searching, hashing) and data structures (linear structures, trees)
• Basics of graph data structures and algorithms
• Algorithmic complexity, logic, probability theory.

These topics are generally contained in books introducing algorithms. For instance, chapters 1-12, 15-17, 22-26, 28-29, 34-35 of (Cormen 09) covers very well the prerequisites

Obiettivi di apprendimento

This module gives the student an overview of frequently used algorithms classes. Based on this strong foundation, students can design and implement the most suitable and efficient algorithms for use in their own applications. The student:
