The TI-Concours in 2017

Categories

This year, we decided to make only one category : z80 and ez80 TI-Basic. For those who are not sure of what it is, recall that it is the Basic language which is available on calculators such as a TI-82 Advanced or a TI-83 Premium CE, and a few other compatible calculators.

Calendar

The contest will be held from March 25th to April 23rd, and will last 30 consecutive days. This year, it is not cut into separate rounds anymore, you will have to manage your time by yourself!

What you will have to do

Earlier today, three different tasks were released simultaneously. Each of them focuses on a specific topic:

• a fun task, that is to say, a game to make;
  
• an algorithmic task, which asks you to solve an algorithmic problem in the most efficient way speaking about speed;
  
• an optimisation task, which requires to produce a sub-optimal solution to a problem and maximize its score.

The goal is the following: in 30 days, solve at least two tasks as well as you can. Of course, you can solve all three of them, but at the end, the final ranking will be based on people's two best scores. For every solved task you will get a score between 0 and 100, but these scores will be harmonized in order to guarantee the fairest possible ranking.


Prizes

If you win, you will enter TI-Concours's legend, and you will thus be covered with honor and glory.
If you think this is not already enough, you may chose one of the following prizes. The winner choses what he wants to get, the second contestant gets what remains.

First prize:

• a TI-Nspire CX CAS;

Second prize:

• a TI-83 Premium CE;

Furthermore, the winner for every single task will win an additional TI-Planet sticker, and all the contestants that get a strictly positive score will win a TI-Planet premium account. 

Other remarks

Everybody can compete. However, in previous editions, people with the highest degree didn't necessarily win...
Please note, that you will not be asked advanced knowledge in topics such as mathematics.

You will have to send your programs by e-mail. All the details are written in the tasks' statements. Be sure that you have a link cable in order to transfer your programs from your calculator to your computer. If you are facing issues related to this, you can ask questions on this forum or on the chat.

One last thing: have fun! We are sure that you will learn something from entering this contest. 

I hope you will have time to.

You still have approximately 23 hours.
