Recently I've read about rotating calipers technique and it's applications from [wikipedia](https://en.wikipedia.org/wiki/Rotating_calipers#cite_note-11). I wonder if there is any articles or blogs from where I can learn more about rotating calipers. I understand convexhull technique . I've searched at codeforces but couldn't find any valuable resources or blog posts. If you guys have any valuable resources on this topic please share. It'll be great if someone writes a blog about this topic at codeforces. Also we can discuss about problems related to rotating calipers here. Thanks for reading :)↵

**UPD:** I just solved [Robert Hood](https://open.kattis.com/problems/roberthood) from Kattis online judge. After spending almost a week I've understood the process of rotating calipers. It feels really great to learn a new problem solving technique. I recommend everyone to read [this book](http://digitool.library.mcgill.ca/R/?func=dbin-jump-full&object_id=21623&local_base=GEN01-MCG02) and visit [this site](http://www.tcs.fudan.edu.cn/rudolf/Courses/Algorithms/Alg_ss_07w/Webprojects/Qinbo_diameter/2d_alg.htm) (provided by [user:SuprDewd,2016-07-25]) for umderstanding rotating calipers technique. [Here](https://ideone.com/TjjhBR) you can find a basic implementation of rotating calipers for finding diameter of a convex polygon. Also don't forget to look at [user:SuprDewd,2016-07-25]'s [comment](http://mirror.codeforces.com/blog/entry/46162?#comment-306705). Thank you all for helping and encouraging me all the time :)
