This course introduces discrete mathematical structures, including data structures and graphs, and examines them from the perspectives of probability theory and optimisation. It then focuses on optimisation in continuous settings, presenting fundamental techniques in numerical mathematics for both linear and nonlinear problems, including the Simplex algorithm, the Newton¿Raphson method, and gradient-based optimisation methods.

Competences

Knowledge

  • K2 - Identify mathematical models and statistical and computational methods that allow for solving problems in the fields of molecular biology, genomics, medical research, and population genetics.
  • K3 - Identify the mathematical foundations, computational theories, algorithmic schemes and information organization principles applicable to the modeling of biological systems and to the efficient solution of bioinformatics problems through the design of computational tools.
  • Skills

  • S3 - Solve problems in the fields of molecular biology, genomics, medical research and population genetics by applying statistical and computational methods and mathematical models.
  • Competences

  • C3 - Communicate orally and in writing with others in the English language about learning, thinking and decision making outcomes.

    Teaching methodology

    The course will be divided between the lectures, that will be of the expository type, and problem sessions in smaller groups solved together, with one typical problem to solve individually and at home for every part of the course.

    Evaluation methodology

    The subject will be assessed by means of compulsory assessment elements which will consist of individual exams, the partial exam and the final exam, and two compulsory tests in the form of small in-class exams to check and orient the learning process of the students.

    The final grade (G) is computed as follows. Both the grade of the partial exam (P) and of the final exam (F) weight 45% of the final grade, and the average of the two in-class exams (C) weights 10% of the final grade. That is:

    G = 0.45*P + 0.45*F + 0.1*C.

    A student is considered to have taken the subject if he/she takes the final exam. In that case, and if G< 5, the student can take the recuperaction exam (R), and the new final grade (G') becomes the maximum between G and 0.9*R + 0.1*C:

    G' = max ( G , 0.9*R + 0.1*C ).

    If the teaching staff considers it appropriate, an oral examination may be conducted to verify the authorship of any of the assessment tests.
