BMath first year courses Linear Algebra-100088 and Fundamental Mathematics-100089.
Discrete Mathematics is a field of mathematics that studies finite mathematical objects or more general discrete mathematics objects. It covers topics such as combinatorics, graph theory, cryptography, error-correcting codes, combinatorial design theory, game theory, logic, optimization, or algorithm design and analysis that can be applied to solve problems in any of the above-mentioned branches. Most of discrete mathematics has evolved relatively recently, motivated by the challenges mainly in computer science and operations research. The chapters of this introductory course are quite independent from one another. A prior knowledge of linear algebra, modular arithmetic, basic combinatorics, and -fundamentally- mathematical language and reasoning should be adequate to understand the subject matter of each chapter.
The first chapter addresses the topic of generating functions and recurrent sequences, this being a natural next step following the elementary combinatorics studied in the first year course Fundamental Mathematics. Once again, problems in combinatorics require training the skill of formulating a problem in terms of a mathematical statement. The second chapter deals with graphs, which are a fundamental tool for problem solving in quite different settings, ranging from the most abstract mathematics up to operations research. In some cases, a graph-theoretical formulation of the problem turns out to be, in itself, illuminating and a highly efficient step towards the solution.
The last chapter it time permits deals with the topic combinatorial optimisation, which deals with combinatoric questions in which, rather than counting objects of a particular type, one is interested in finding "the optimal" ones with respect to some criterion. The answers in this case won't be given by formulas but by algorithms to find or approach such optimal objects. The theory used involves basic linear algebra techniques (for linear programming) and matroids.
In summary, throughout this course in discrete mathematics, a variety of examples and applications will be explained, where by means of relatively simple tools and a clever approach, we get to solve interesting and difficult problems. Moreover, by their work on problem sets, students will be able to practice the first step in the process of mathematical modeling, namely, understanding a problem and finding a suitable mathematical formulation that leads to the solution.

There are four graded tasks: a midterm exam, a computer lab test, a seminar project, and a final exam.
Course grade is calculated according to the following formula:
0.2 midterm exam score + 0.2 computer lab test score + 0.15 seminar project score+ 0.45 final exam score
Exam Retake Option: There is only one possible retake for the written exams (65%). To be eligible to retake the final exam you should have participated, at least, in three graded tasks.
Participating in less than three graded tasks and not taking the final exam will result in a "Non-assessable" course grade.
The course ``Seminari de Matemàtica Discreta" may only be avaluated by the previous description.
