ICO Computing Science Syllabus

Students need to focus on the topics of Fundamental Data Structure for taking the ICO exam:

Regarding floatingpoint numbers, there are wellknown reasons why they should be, in general, avoided at the IOC. However, the currently used interface removes some of those issues. In particular, it should now be safe to use floatingpoint numbers in some types of tasks, e.g., to compute some Euclidean distances and return the smallest one.

 The concept of recursion
 Recursive mathematical functions

Algorithms and Complexity (AL)
Algorithms are fundamental to computer science and software engineering. The realworld performance of any software system depends on the algorithms, the suitability, and the efficiency of the various layers of implementation.
Good algorithm design is, therefore, crucial for the performance of all software systems. Moreover, the study of algorithms provides insight into the intrinsic nature of the problem as well as possible solution techniques independent of programming language, programming paradigm, computer hardware, or any other implementation aspect.

Important Guidelines for Indian Computing Olympiad
There are several reasons for imposing restrictions on concepts, terminology, and notations in ICO competition tasks.
Given below are the instructions and guidelines to be followed by the Indian Computing Olympiad.
 The ICO competition is not intended to test knowledge, and it assesses algorithmic problemsolving skills. Many contestants have not yet completed secondary education. Therefore, the ICO organizers cannot assume that contestants have much prior knowledge of concepts, terminology, and notation in algorithmic problems (or any other area, for that matter).
 ICO contestants come from all over the world and have diverse educational backgrounds. The organizers should aim at formulations that are understandable by all contestants.
 Concepts, terminology, and notations used in computing science are fraught with complications. CS professionals have learned to cope with many years of training. For example, the concept of a graph is rather vague as such. It requires many additional details to make precise what is meant. A CS professional can often infer these details from subtle clues in the context. It cannot be expected from an average ICO contestant.
Indian Computing Olympiad Preparation
During the preparations for ICO competitions, candidates should prioritize the appropriateness of concepts, terminology, and notations used in competition tasks that have been discussed and decided. It is because it has often led to changes in task descriptions.
Let us first clarify what we mean by concept, terminology, and notation.
 Concepts refer to a general idea with a specific focusfor instance, the concept of a number and incidence (in geometry). Often, a concept is not atomic but a composite of (simpler) concepts.
 'Terminology' refers to the typical words used in connection with a conceptfor instance, the elements of a set, appointed online.
 'Notation' refers to the typical (mathematical) symbols used in connection with a concept. For instance, {0,1,2} denotes the set consisting of the three numbers 0,1, and 2.
 We distinguish three classes in the usability classification. In order of increasing restrictiveness, these are
 Basic knowledge (BK): can be used without further definition.
 Tobedefined (TBD): This can be used but needs to be defined explicitly.
 Tobeavoided (TBA): cannot be used.
Note that, for a given concept, the related terminology and notations may end up in different classes. The classification presented here was obtained as a combination of,
 Personal experiences gathered during meetings at past ICOs.
 Personal experiences from teaching and organizing programming contests.
 Analysis of task descriptions of past ICO competitions.
 Discussions with various members of the ICO community.
