Cemetech Contest #15: Crypto Golfing
Published by KermMartian on December 15, 2015 at 6:45:07 PM CST | Discuss this article (70)

Last month, we resurrected Cemetech programming contests with Cemetech Contest #14: TI-BASIC Connect 4 AI Challenge. In that short contest, designed by Cemetech members jonbush and earthnite, entrants were tasked with writing an AI to play Connect 4 in pure TI-BASIC. We congratulate JWinslow23 for winning that contest, and are happy to announce a longer, more elaborate contest. Cemetech Contest #15 is entitled Crypto Golfing, and is a multi-part contest. Starting today, and continuing every Tuesday until January 12th, we will release encrypted data with possible hints for a new challenge. Your mission, should you choose to accept it, is to create a program to decode each piece of encrypted data, be it a string, a number, an image, or something else, in as few bytes as possible. The top two overall winners will win a TI-84 Plus C Silver Edition and a TI-Nspire CX (with the first place winner getting first choice).

As in previous Cemetech contests, we'll have a number of categories; the sizes of entries from each category will be weighted at the discretion of the judging panel.
  • TI-83 Plus/TI-84 Plus TI-BASIC, ASM, C, or Axe: Programs in any of these languages for any calculator with "TI-83 Plus" or "TI-84 Plus" in its name will be accepted, including the TI-84 Plus C Silver Edition and TI-84 Plus CE. Hybrid TI-BASIC and z80 ASM programs must use only the libraries available in Doors CS or Doors CSE, to make grading easier.
  • TI-Nspire CX and HP Prime: Lua entries for the TI-Nspire CX and CX CAS as well as PPL programs for the HP Prime will be accepted.
  • Computers: Java, Javascript, C++, Rust, Haskell, and Python: For those who focus on computer programming these days, computer programming solutions will be accepted in the languages listed. Want to write in another language? Let us know what that language is in the attached Cemetech topic, and we'll consider it.

The usual rules apply:
  • Contestants may not release any code or binaries before the end of the contest, including asking for programming help publicly or privately. Violators will be disqualified. Projects that have already been released in any form (excluding a contest project topic) already are not eligible for the contest.
  • The contest will run until January 19th, 2016, at 11:59:59pm Eastern Time. No late entries will be accepted. Entries to any of the five challenges will be accepted up until this deadline. The earlier you submit each challenge's solution, the higher your score!
  • All contestants must maintain a topic in the Contests subforum on Cemetech, including a first post that mentions the programming language(s) you'll be using. You can also post the size of your entries and when you complete them. Do not post algorithmic solutions, code, or hints.
  • Submit entries by emailing them, in a zip file, to contest at this domain name. Be sure to provide your Cemetech username in the subject or body of the email so we know who you are! Each Cemetech member can submit a single entry in one or more of the accepted language + platform combinations.
  • Judging will be performed by a team picked from among the Cemetech administrators and members; all judges are disqualified from entering the contest. Results will be posted no later than ten days after the end of the contest.
  • Algorithmic grading will be performed, based on the size of each entry's source code (or for assembly, assembled binaries) and how early the entry was submitted. Speed will not be graded.
  • As with the Contests #12 and #13, we are very proud to offer two brand-new calculators as prizes. The grand prize winner will be awarded one TI-84 Plus C Silver Edition or one TI-Nspire CX, as chosen by the winner. The second-place winner will receive the remaining calculator. Additional Cemetech swag may be added to the prizes at the Cemetech staff's discretion. All participants will earn Cemetech flair in the form of signature bars and respect.

So what are you waiting for? Get coding, solve Challenge 1, push yourself to learn something new in the process, and win some calculators!
