ECTS Credits: 6.0 ECTS


Requirements (Subjects that are assumed to be known)
Programming Algorithms and Data Structures
The objective of this course is for the student to acquire the following competencies and learning outcomes: 1.- General and Basic Competencies: CGB3 - Ability to understand and master the basic concepts of discrete mathematics, logic, algorithmic and computational complexity, and their application to solve engineering problems. CGO9 - Ability to solve problems with initiative, decision making, autonomy and creativity. Ability to know how to communicate and transmit the knowledge, skills and abilities of the profession of Technical Engineer in Computer Science. CB1 - That the students have demonstrated to possess and understand knowledge in an area of study that starts from the basis of general secondary education, and is usually at a level that, although it is supported by advanced textbooks, also includes some aspects that involve knowledge from the forefront of their field of study. CB3 - That students have the ability to gather and interpret relevant data (usually within their area of study) to make judgments that include reflection on relevant social, scientific or ethical issues. CB5 - That students have developed those learning skills necessary to undertake further studies with a high degree of autonomy. 2. Specific competences: CECRI5 - Knowledge, administration and maintenance of computer systems, services and applications. CECRI6 - Knowledge and application of the basic algorithmic procedures of computer technologies to design solutions to problems, analyzing the suitability and complexity of the proposed algorithms. CECRI15 - Knowledge and application of the fundamental principles and basic techniques of intelligent systems and their practical application. 3. Learning outcomes: R1 Knowledge and understanding: have basic knowledge and understanding of the scientific and technological foundations of Computer Engineering, as well as a specific knowledge of computer science, computer engineering and information systems. R5 Engineering Applications: Graduates will be able to apply their knowledge and understanding to solve problems, conduct research, and design devices or processes in the field of Computer Engineering according to criteria of cost, quality, safety, efficiency, environmental friendliness, and ethical implications. These skills include knowledge, use and limitations of computer systems, process engineering, computer architectures, computational models, equipment, practical work, technical literature and information sources.

Learning activities and methodology
THEORETICAL-PRACTICAL CLASSES (theoretical content): 3.5 ECTS. The knowledge to be acquired by the students will be presented. They will receive the class notes and will have basic reference texts to facilitate the follow-up of the classes and the development of the subsequent work. Exercises will be solved by the student that will serve as self-evaluation and to acquire the necessary skills. Classes of problems, in which the problems proposed to the students will be developed and discussed. WORKSHOPS AND/OR LABORATORY PRACTICES. 1.5 ECTS. Developed with or without the presence of the teacher, they aim to complete and integrate the development of all the specific and transversal competences, in the resolution of two practical cases where the approach to the problem, the choice of the resolution method, the results obtained and their interpretation are well documented. FINAL EXAM. 0,5 ECTS The knowledge, skills and abilities acquired throughout the course will be globally assessed. TUTORIALS. 0,5 ECTS Individualized assistance (individual tutorials) or in group (collective tutorials) to the students by the professor.
