ICPC Challenge

2012 ICPC Challenge

The ICPC Challenge gives programming teams and their coaches a chance to work on a different kind of problem. Working with their coach, teams implement a player and compete against other teams' players in a new game called ICPC Bumper Boat Rally. Preliminary matches during the two-week coding phase helped teams to develop and refine their players. Now, we're preparing for the final tournament.

Final Tournament

We're preparing for a final tournament in Warsaw, Poland. We will use the following, double-elimination tournament tree. It's based on the preliminary standings from the end of the coding phase. Sorry some of the names are long here. We'll get a list of short institution names before we run the tournament.

Playing Along

It's too late to participate in the 2012 ICPC Challenge, but you can still try out the game and see about coding a player yourself. The following links give you everything you need to get started.

ICPC Bumper Boat Rally

The ICPC Challenge game, ICPC Bumper Boat Rally, is played in an environment that looks something like the following figure. A red player and a blue player compete to pilot their boats around a course. Each player directly controls a fleet of five boats of various configurations. As the name suggests, these boats aren't top-of-the-line water craft; they're more like the kind of boat you might find at an amusement park. The game rules describe how to pilot the boats and how to complete laps. All you have to do is figure out how to win.

Illustration of the Game

Writing your Player

Your player will be implemented as a stand-alone program, in C++ or Java. You will interact with the game by reading information about the game world from standard input and writing your next move to standard output. The sample players can be a quick way for you to get started writing your player and interacting with the game. A more detailed description of the execution environment explains the input and output format for your player as well as other rules for what your player can do.

Running a Match

Once you have a player written, you can run it by starting up the game and pointing it to your player's executable. If you have written a player in C++, you can run it against the sample Java player using a command like:

java -jar bbr.jar -player cpp myPlayer -player java -cp java_example HotPotato

If your player is implemented in Java, you can have it play (as the blue player) against the Java example using a command like:

java -jar bbr.jar -player java -cp java_example HotPotato -player java MyPlayer 

The more detailed usage instructions describe additional options for starting up the game, including how to capture a match as a trace file and how to debug your player during execution.

Submitting your Player

During the coding phase of the competition, players can access the competition through the ICPC Challenge site at: http://icpc.baylor.edu/challenge/ From this page, participants will be able to login to the submission system, submit player code, and see how they are doing in preliminary matches. The latest working submission is considered the participant's current player. The final tournament and the nightly preliminary matches will use the most recently submitted player code that successfully builds.

All source code and supporting files for a player must be submitted at the same time. From the submission interface, select each source file that's part of your player, and then press the "Upload Files" button to upload the whole thing. If you forget to submit an important file, you will need to re-submit everything to have a working player.

Changes and Corrections

If we encounter a critical problem, we'll notify coaches via email. For smaller problems and clarifications, we'll just provide a note here.

Additional Information

The ICPC Challenge website, http://icpc.baylor.edu/challenge/, will provide regularly updated information during the coding phase of the competition. If corrections or clarifications are needed, they will be linked from here.

About the ICPC Challenge

The ICPC Challenge is an effort to continue to offer the kinds of visual, interactive, competitive programming problems popularized by previous offerings of the Java Challenge. Teams implement player code that competes with other teams' players in a game-like simulation. A tournament among the players determines the winner.

Queue ICPC Challenge

Working together, the ICPC and ACM Queue Magazine have offered a challenge problem for interested queue readers. In January and February, we offer a head-to-head programming problem, and anyone who's interested can join in and compete. Even if you've never competed in the ICPC, you can join us for the Queue ICPC Challenge and show what your programs can do. Visit the Queue ICPC Challenge site to find out more about this contest and how you can get involved.

2011 ICPC Challenge

The 2011 ICPC finals featured an ICPC Challenge problem called coercion. Teams developed a program to try to claim teritory on a map by pushing around markers and then using these to convert map regions to their own color. See the 2011 ICPC Challenge Page for a description of the problem and the winners. You can also check out preliminary standings from the coding phase of the competition and see the results of the final tournament. You can even watch videos of the matches. If you want to try the problem for yourself, you can download the game binary and write your own player.

2010 ICPC Challenge

The 2010 ICPC finals featured an ICPC Challenge problem appropriate to the February weather in Harbin, China. Teams developed a program to control a group of children in a snow-covered field. See the 2010 ICPC Challenge Page for a description of the problem and the winners.

2009 ICPC Challenge

The 2009 ICPC finals featured an offering of the ICPC Challenge. The 2009 ICPC Challenge Page describes the challenge problem from that year and gives the preliminary standings from the coding phase of the competition. You can see the results of the final tournament and even watch videos of the matches. If you want to try the problem for yourself, you can download the game binary and write your own player.
