Course 2018-2019 a.y.

• Introduction to Python's Numerical and Scientific libraries (numpy, scipy, matplotlib...). This is a must for real-life data analysis and numerical computing in Python.

• Randomized algorithms: Monte Carlo methods for sampling and numerical integration, and the Simulated Annealing optimization algorithm. This is a simple but deep optimization strategy with wide applicability. Also allows the demonstration of the interface programming pattern.

• Non-linear programming: Basic techniques for continuous optimization in the non-linear case: first- and second-order methods in one dimension, later extended to the multi-dimensional case. The "gradient descent" strategy is of particular importance in modern-day machine learning. Also, allows the demonstration of the use of multi-dimensional tensors in efficient numerical programming.

• Dynamic programming: A wide range of discrete problems can be solved elegantly and efficiently by this "implicit enumeration" general scheme. This is an algorithmic pattern, and students learn from examples to recognize the applicability of this technique. This is a valuable general skill, and this particular case is extremely useful in practical settings. The coding techniques involved offer many opportunities to demonstrate how to write efficient numerical algorithms, and how to implement a general pattern adapting it to a particular situation.

• Recognize discrete/continuous optimization problems and their class.
• Express algorithms in vectorized form, e.g. leveraging numpy's broadcasting mechanism.
• Master some intermediate programming patterns and paradigms, like interfaces and some functional programming.

• Translate an optimization problem in mathematical terms.
• Having identified the most suitable solution technique among the ones presented during the course, write the corresponding code.
• Identify suitable parameters for heuristic optimization algorithms, based on the knowledge of their properties and exploratory analysis.

• Face-to-face lectures
• Exercises (exercises, database, software etc.)

Programming exercises are used after each practical session to guide the students into:

• Autonomously extending the code functionality and/or adapting it  to modified situations.
• Exploration of the properties of heuristic solvers.

The exam has two separate parts:

• A theory part, written with open-ended questions, intended to assess all the theoretical learning objectives of the course.
• A programming exam, held in the computer room, consisting in a series of programming assignments, intended to assess all the practical learning objectives of the course.

The two parts have an equal weight: each is worth 16 points. Each part individually has a minimum passing grade of 9. The sum of the two parts gives the final grade, with votes exceeding 30 corresponding to "30 cum laude".
