Video Library
Lecture videos for every topic in Units 1β3. Watch to get a method, then come back and write it from the notes.
Every link has been verified live β the video exists, and the title and channel shown are the real ones, checked programmatically against YouTube's oEmbed API. One candidate came back dead and was replaced.
Timestamps are not given. Reading a video's chapter markers requires loading the video page itself, which is not possible from this environment. Rather than print plausible-looking timestamps that might send you to the wrong minute, none are shown. Most of these are single-topic videos where the whole video is the relevant section.
Unit 1 β Formulation & Graphical Method

Most transportation videos continue into North-West Corner Rule, Least Cost Method, VAM and MODI, and most assignment videos continue into the Hungarian Method. Those algorithms are not in your notes and neither paper asked for them β see the Unit 3 scope note. Watch the formulation portion; treat the rest as optional background unless your class covers it later.
- Watch once, then close the tab and redo it on paper. Following along feels like learning and is not.
- For duality and sensitivity, the video is background β the marks are in the mechanical procedure. The Formula Sheet is what you actually reproduce under time pressure.
- Skip anything that solves what your paper only asks you to formulate. Both 2025-26 papers said "Formulate" on every LPP, ILP and transportation question.
