Core GATE CSE Subjects 30 topics High — every year

Algorithms

GATE CSE Algorithms — asymptotic analysis, sorting, graph algorithms, greedy, and dynamic programming.

Learning outcomes

  • Compare Θ, O, and Ω on standard examples
  • Apply BFS, DFS, Dijkstra, and Kruskal/Prim ideas
  • Set up a simple DP recurrence
  • Spot the right algorithm from a problem stem

Overview

Algorithms questions test complexity, standard sorts, BFS/DFS, shortest paths, MST, greedy choice, and DP recurrences.

You do not need to write long code — you must recognize the algorithm and compute a result or complexity.

Revise proofs of correctness only at the level GATE asks (invariants, greedy stays safe, overlapping subproblems).
