Subject Overview: The Efficiency Engine
Algorithms is the intellectual heart of Computer Science. In GATE, it tests your ability to think recursively and optimize for time and space. It is a high-yield subject, consistently contributing 8–11 marks. To score full marks, you must master asympototic notation and the "Divide & Conquer" logic used in sorting and searching.
| Topic | Expected Marks | Difficulty | Frequency |
|---|---|---|---|
| Sorting & Searching | 2–3 | Easy | Very High |
| Dynamic Programming | 2–3 | Hard | High |
| Graph Traversal (BFS/DFS) | 2 | Medium | High |
| Asymptotic Analysis | 1–2 | Easy | High |
| Greedy Algorithms | 1 | Medium | Medium |

Pro-Tip: The 'Recurrence' Hack
When faced with a recurrence relation like $T(n) = aT(n/b) + f(n)$, always check the Master Theorem conditions first. If it doesn't fit, use the recursion tree method—it is the most reliable way to visualize nested complexity.
Logic: BFS vs DFS
Remember: BFS uses a Queue (for shortest paths in unweighted graphs). DFS uses a Stack (for topological sorting and cycle detection). This fundamental distinction solves 80% of graph theory questions in GATE.
