Mission & Content Summary

MISSION

The course will teach the students the fundamentals of designing and analyzing algorithms for optimization and inference problems. The students will be able to estimate the computational complexity and the resource requirements of the algorithms they encounter, and to use them as building blocks in their own work. They will be familiarized with fundamental algorithmic theory and optimization techniques, and their interplay with inference and learning methods.

  • Design and analyze efficient algorithms
  • Estimate the computational and resource requirements of algorithms 
  • Classify optimization problems according to their computational complexity 
  • Formulate optimization problems as Linear/Integer/Non-linear programming models

Teaching methods

  • Face-to-face lectures

DETAILS

The teaching method is face-to-face lectures. Several lectures will include exercises to be done in class.


Assessment methods

  Continuous assessment Partial exams General exam
  • Written individual exam (traditional/online)
    x
  • Individual assignment (report, exercise, presentation, project work etc.)
x    

ATTENDING AND NOT ATTENDING STUDENTS

There will be a written exam and two homework assignments. The homework assignments are not mandatory.

The final grade will be calculated by taking for each student the best outcome out of the following two ones:

(a) Final written test contributes 70% of the final grade, and homework assignments contribute 30%.

(b) Final written test contributes 100% of the final grade.

 

The exam will test the students' ability to explain and reproduce the concepts learned in class, and connect these concepts to specific problem instances. There will be no difference between attending and non-attending students.
