Training roadmap for newcomers

Revision en2, by mostafa.saad.fci, 2019-11-14 21:07:13

I used to encourage newcomers in our community to train using this sheet to avoid random training. By the end of the sheet, one will be very good up to Div2-D. It has been refined several times based on the received feedback.

Please, check out the sheet before reading. The sheet is

  • Complete and consistent roadmap for newcomers: What to solve & algorithms to learn in order

  • In the bottom row, there are different sheet pages such as Faq, Topics, CF-C2

  • CF-C1, C2 are (Codeforces Div2 C problems (or similar level from other OJs), but from easy to hard). Same for CF-D1, D2, D3

  • Covering most of the topics needed up to Codeforces Div2-D

  • Problems increase in difficulty per topic with intermediate easy/medium problems + ad-hoc problems

  • Speed problems to maintain speed goals


One can train in one of the following ways:

A) Blind-Order training style

  • Problems are distributed in sheets CF-A, CF-B, CF-C1, ....CF-D3

  • It targets learning the knowledge/skills in a consistent and balanced way

  • Every sheet page is on average harder than the previous sheet page

  • This is my recommended way, though most camps/training-approaches don't use this style

B) Topics-Based training style

  • See the sheet page (Topics1). It has the same sheet problems (CF-A to CF-D3) ordered by category and level, around 950 problems. Also checkout Topics2 page

  • Ideas Quality column: P5 (important), P4(very interesting), P3(interesting), P2(good), P1(ok), Empty (normal)

  • You can train using Blind-Order, and use Topics page as a guide to skip some problems

  • Advantage: Mastering the algorithm till solving some hard problems in a short time

  • Disadvantage: Discovering the algorithm behind the problem is an important skill. Given that you know the topic, you lose a good space to improve this skill

  • Disadvantage: Being in the mode of specific algorithm lets you solve many of it easier. However, when solving in real contests, your mind is not so active on the specific topic
