Hi people!↵
↵
I recently published a platform to host custom Codeforces contests. This was a personal project I worked on (as a contribution to an introductory undergraduate course I TA'd) to serve as a means of hosting mock ACM competitions for training purposes.↵
↵
### Features↵
↵
So far, it has been used in no less than 10 contests, which helped with enhancing it and adding more useful features, including:↵
↵
- Auto-updating scores↵
- Blind time↵
- Varying problem weights/points (an option to manually set the more difficult problems to yield a higher score)↵
- Cancelling certain submissions↵
- Verifying which of the entered problems were solved by the given user handles (could be used to ensure none of the contest problems was pre-solved before the contest)↵
- Logging a detailed report of the given handles, showing their submissions' details in a certain time-frame (or all time)↵
- Copying/Loading a contest using an compressed string (to help setup the same contest across multiple rooms/computers)↵
- Color-coded scoreboard indicating first submissions, accepted answers, and attempts↵
↵
### Scoring↵
↵
Currently, the scoring system works as follows:↵
↵
1. Each individual problem has it's own linear-based time penalty. The way it works is by calculating how many points should be lost per minute if the problem points are to be _halved_ by the end of the contest (since both the contest duration and problem points are variable)↵
2. All penalties/bonuses are in terms of **time** (minutes)↵
3. Each wrong answer results in a 10 minutes penalty (10 minutes' worth of points)↵
4. Program efficiency adds bonus points; 20 minutes for a 15ms time-consumed submission↵
↵
This scoring formula can be changed/customized. I tried to think of a fair way to cover all grounds, but it could be flawed (if that's the case, please suggest ways to improve it)↵
↵
↵
### Finally...↵
↵
I open-sourced this [project](https://github.com/ThunderStruct/ACM-Scoreboard) to allow people to contribute and modify it to suit their needs. The markdown README contains a fairly thorough documentation of all the tools available and some helpful tips for customization and contribution.↵
↵
It's also hosted [here](http://www.thunderstruct.com/acm-scoreboard/) for convenience.
