Conoscenze e abilità da conseguire
At the end of the course, the student has the basic Knoledge in design and analysis of correct and efficient algorithms and data structures. In particular, the student has basic knowledge on algorithms and data structures. The student will be able to: design correct and efficient algorithm for common computational tasks; analyze existing algorithms and data structures; design and analyze new algorithms and data structures.

Metodi didattici
The course is structured with live lessons, illustrating the theoretical aspects of the topics concerning the data structures and algorithmic design for computational biology. After the introduction of basic definitions and concepts, the course illustrates the design of simple data structures and the relationship with the costs of execution (computational efficiency) and memory occupation (space) on the computer architecture. Some results are presented and demonstrated concerning the design of efficient algorithms and their relationship with efficient and well designed data structures, functional to the algorithm execution. Some programming and algorithmic design techniques are introduced and discussed in terms of computational and space complexity: iterative, recursive, divide et impera, greedy, dynamic programming. Finally, space is given to the application of design concepts towards the realization of solutions for exercises and analysis methodologies in bioinformatics and molecular biology. In addition to the live lessons, live exercises in class are provided.
Modalità di verifica dell'apprendimento
The final exam is composed of a written part (3 hours) and possibly an oral part (30 minutes). During the written part, it is NOT allowed the use of books and notes, calculator and communication devices, including Internet access. The written part is composed of two sections: the first section concerns the design and analysis of algorithms and data structures oriented to the maximum computational and space efficiency by adopting the techniques and knowledge learnt during the classes. Specifically, the candidates must develop the pseudo code of the algorithm and the corresponding well designed data structures, by commenting and motivating the choices made, and defining the space and time complexity of execution. The first exercise will takes more or less 90 minutes, and the weigth of the score is more or less 50% of the total score. The second section of the written part concerns exercises on the topics of the classes, including interpretation and design of the concepts learned. Such exercises are derived and similar to those made in class. The time limit is 90 minutes and the weight is more or less 50% of the total score. The calendar of written exams is provided by the end of the classes, and at least one writen exam session is allocated in June, July, September, October, December and February. It is mandatory to subscribe to the list of participants on almaesami within the announced deadlines. Provided that the candidate passes the written exam (with evaluation greater or equal to 18/30), s/he may be scheduled for the oral part in case the written exam evaluation is low. In that case, to pass the course, it is mandatory to receive a sufficient evaluation in both the written and oral parts.
