Principles Of Computer Science 2

Second Year / First Semester Course L-2 - 1049261

(A. A. 2017/2018)


The course aim to introduce computational thinking and the algorithmic approach to solving problems correctly and efficiently. Algorithms are ubiquitous in bioinformatics and are often at the interface of computer science and biology. Well established algorithmic techniques will be studied as well as ways to encode them in a computer program using python.

We will introduce the algorithmic approach and the theory of algorithms for studying correctness and efficiency, understanding what makes a good algorithm and how to classify them.

We will study characteristic algorithmic techniques and the relate-d computational ideas that are relevant to the field of biology and how to select the most suitable to solve a given task. Topics covered include

  • Searching algorithms
  • Divide-and-Conquer algorithms
  • Clustering and Tree-based algorithms

We will work with Python and how to write a computer program encoding a given algorithm.
