11 pages, one purpose each

  1. p. 1Cover, contents and how to useThe page map, a key to every box type, and the order to read on the last day.
  2. ALG-02Asymptotics, Recurrences and the Master TheoremHow fast does it grow, and which rule solves this recurrence?
  3. ALG-03Searching and Sorting Master TableWhat each search and sort costs, and what it keeps
  4. ALG-04Divide and Conquer and Greedy MethodsWhen splitting or a local best choice is right, and its cost
  5. ALG-05Dynamic Programming Recurrences and TablesThe state, recurrence and table cost of each classic DP
  6. ALG-06Graph Traversals: BFS, DFS and Topological OrderWhat BFS and DFS compute; edge classes and DAG order
  7. ALG-07Minimum Spanning Trees and Shortest PathsWhich algorithm fits the weights, and what survives a reweighting
  8. ALG-08Algorithm Selection: If You See This, Think of ThisFrom the question wording to the algorithm and its bound
  9. ALG-09GATE Traps SheetThe wrong turns that cost marks, each with the rule that fixes it
  10. ALG-10Question Patterns and Solving ApproachRecognise the pattern in the stem, then run the matching routine
  11. ALG-11Master Last-Day Revision SheetEverything to reread on the last evening, one page

How each page works

Built for fast revision

  • Quick Recall boxes: the facts to hold in memory
  • Formula boxes with variables, when each applies and the usual mistake
  • Students Think / Actually: the wrong intuition next to the correct rule
  • If You See This / Do This: a cue in the question and the steps to take
  • Compare tables for look-alike concepts
  • Trap boxes: a known wrong turn and its fix
  • Edge cases that change the answer
  • Decision flows to run in order
  • Master tables for quick lookup
  • Worked mini-examples
  • Diagrams

About this pack

Scope

Revision pages for Algorithms in the GATE CS 2027 syllabus: asymptotics, recurrences and the master theorem, a searching and sorting master table, divide and conquer and greedy methods, dynamic programming recurrences and tables, BFS, DFS and topological order, minimum spanning trees and shortest paths. An algorithm selection page maps the cue in a question to the method to use. Every count and bound with a number was checked by a script, and solved past questions were computed by compiled C programs. Hashing is in the Data Structures pack.

Before you buy

Common questions

What exactly will I receive?

A 11-page A4 PDF in two editions: a screen edition for reading on a device and a print edition prepared for A4 printing. Nothing is shipped; it is a download.

Can I read it on my phone, and can I print it?

Yes. The PDF opens in any PDF reader on phones, tablets and computers, and the bookmarks jump between pages. You may print it for your own study.

Is it for GATE 2027?

Yes. The packs follow the official GATE CS 2027 syllabus, and each pack says what is in scope and what is covered in another pack. GATE CS Mastery is independent and not affiliated with IIT, IISc or the GATE organising committee.

How is this different from ordinary short notes?

Each page answers one question and uses labelled boxes: rules with their conditions, traps with the fix, comparison tables and small worked examples. Every pack ends with a traps sheet, a question-patterns sheet and a one-page last-day sheet.

What happens after I pay?

When Razorpay confirms the payment, download buttons appear straight away and a receipt is emailed to you. Later, My library sends a one-time link to your purchase email and shows fresh download links.

What if the payment succeeds but the download fails?

Do not pay again. Your purchase is recorded as soon as the payment is verified. Open My library, or write to support@gatecsmastery.com with your order ID or Razorpay payment ID. See the refund policy for when a refund applies.
