JNTUK R20 CSE Branch students can access the Unit-wise R20 2-1 Mathematical Foundations of Computer Science (MFCS) Material/Notes/Test Books PDFs provided below. The course aims to provide a comprehensive understanding of the following:

• Introducing the students to the topics and techniques of discrete methods and combinatorial reasoning
• Presenting a wide range of applications that reinforce the close ties between discrete mathematics and computer science

By the end of the course, students will be able to:

• Solve mathematical problems with ease
• Comprehend mathematical principles and logic
• Demonstrate knowledge of mathematical modelling and proficiency in using mathematical software
• Analyze and manipulate data using appropriate software
• Communicate mathematical ideas and results effectively through verbal or written means

The course is divided into five units:

1. Unit 1: Mathematical Logic
2. Unit 2: Set Theory
3. Unit 3: Combinatorics and Number Theory
4. Unit 4: Recurrence Relations
5. Unit 5: Graph Theory

Each unit covers specific topics and techniques, and students can download the PDFs for each team from the provided links. The course also provides recommended textbooks and reference books for further reading and clarification.
