halite.io reminds me of screeps on steam

  Ah yeah I forgot to mention screeps which is awesome!

Great list, thank you

Are there any on the list here that are best for learning algorithms in a manner similar to a course curriculum and has explanations? I'm asking from a self-taught web dev (django) perspective where I have holes in my knowledge. Some algo books I have so far seem too mathy. While not afraid of math, I understand it better when coding them out myself. I wish projecteuler would provide more hints/explanations. Adventofcode problems are fun but are random (not like a curriculum). Other websites are competitive programming focused which I'm not sure is comp-sci enough (correct me if I'm wrong).

  Not on the list, but you might find http://interviewbit.com http://interviewbit.com more structured

    Yeah, +1 for InterviewBit. Courses here are a way more structured and gamified.
- 10-6 8y ago
  So for beginner/intermediate alg/data structures challenges with explanations and solutions I would recommend the following resources: 1. Read the Algorithm Design Manual. 2. Practice coding simple and then more advanced algorithms on sites like Coderbyte (aimed at beginners -> intermediate) and HackerRank (a bit more mathy). 3. Read as many algorithm explanations and code examples as you can on GeeksforGeeks. 4. Try and implement basic algorithms yourself like: shortest path, minimum spanning tree, DFS/BFS, tree traversals, different sorting algs, min/max heap, etc. and learn their running times. * Also this article may be helpful for you: https://medium.com/coderbyte/how-to-get-good-at-algorithms-data-structures-d33d5163353f https://medium.com/coderbyte/how-to-get-good-at-algorithms-d...

  I can recommend 2 books "competitive programmer handbook" and "algorithms unlocked" - none of these books is too mathy

  Leetcode seems like something u are looking for as well

http://www.hakank.org/picat/ http://www.hakank.org/picat/ has the most examples, good explanation of the problems, and elegant, short solutions.
