TEN THINGS YOU NEED TO KNOW TO MAKE YOUR OWN CONTEST:
1. What is the difference between open and private contest?
Criteria	Open Contest	Private Contest
Problems	Only new problems	New problems and/or existing problems
Competitors	All users can participate	Only invited users
2. What problems can and can't be part of my contest?
It will only be accepted problems written by the creator of the contest or by another author with written authorization.
You can use the problems available at our repository only for Private Contests. It is forbidden to use or replicate them without our written authorization.
The author of the contest will answer acording to the Brazilian Law for any unauthorized use of the problems.
3. How many problems can my contest have?
Each contest is made up of at most 13 problems.
4. How should I format the problems of the Contest?
Yes, all the problems should be formatted with the URI Online Judge Builder (www.urionlinejudge.com.br/builder). For necessary files to be generated, you must complete all the fields in Portuguese and English.
Please informe the category, subject and estimated level of difficulty of each problem.
Rename the files generated by the Builder following specification:
Description in Portuguese (X.html);
Description in English (X_en.html);
Configuration File (X.yaml);
X is a letter from A to M indicating the order the problem should be registered.
The title must be in Camel Case, that is, the first letter of each word in uppercase, as shown in the example below.
​
Figure 1. Header formatting style.
You must boldfacing only variables in the input and output specifications (never in the problem description). You can use italic in the description to represent variables or any other importat information.
​
Figure 2. Description formatting style.
The limits and restrictions should appear in parentheses after each variable. For example: "The input contains an integer T (0 < T < 100) ...". Different restrictions for the same variable must appear within the same parentheses and you should use asterisks to differentiate them.
​
Figure 3. Different restrictions for the same variable.
You must identify the contest in the footer of each problem. For example: "My Contest Contest - 2014".
Regarding the paragraphs is important to know that:
They must be between the tags <p></p>;
They should not be broken by <br /> tags;
They should not be justified;
They should not use different font styles.
Note: The system automatically applies the style rules (CSS) when the files are generated.
5. How many and which files should I send?
Altogether there are approximately 8 files:
The HTML file with description in Portuguese (X.html);
The HTML file with description in English (X_en.html);
The configuration file (X.yaml); ;
The necessary images files (optional) identified by the letter of the problem and a sequence (A_01, A_02, B_01, ...);
Preferably 2 files with source code in C++ (.cpp): one with a solution that should receive "Accepted" and the other one that should receive "Time Limit Exceeded" so we can determine the timelimit of the problem according to our server;
One input file (.in) with maximum size of 12MB*, creted on Linux. If you create this file on Windows should take care with the line break. For Linux (UNIX), the default is LF whether for Windows the default is CRLF. This difference will generate "Presentation Error";
One output file (.sol) with maximum size of 12MB* following the same restrictions described above.
* This is a temporary measure to avoid long queues. 6. What is the maximum timelimit for problems?
The timelimit should be at most 7 seconds. If you really require a large timelimit, please let us know. Remember that large timelimits can create judging queues.
7. What is the deadline to send all the files?
Contests made up of at most 6 problems: 48 hours before the contest;
Contests made up of more than 6 problems: 72 hours before the contest.
8. What are the clarifications and how to access them?
The clarifications serve to facilitate communication between the creator of the contest and the contestants, who can through this feature, clarify any questions or communicate any relevant information during the competition.
The exclusive link to access the clarifications page will be provided by the URI Online Judge team the day before the contest.
9. Can I change the problems during the competition?
Yes it is possible, however we strongly recommend not to. Only in extreme cases there will be changes and these will be made by the URI Online Judge team after evaluation.
