The Challenge

Use the APL programming language and your problem solving skills to compete for cash prizes and a paid trip to the annual Dyalog user meeting in Northern Ireland, UK.

Don't know APL? Don't worry! Most of the winners of previous competitions were new to APL yet quickly learned enough to submit excellent entries.


Grand prize

$2,500 cash prize and an invitation to attend the 2018 Dyalog user meeting (to be held in Northern Ireland from October 28 - November 14, 2018). At the user meeting the winner will receive their prize and have the opportunity to present their winning work. Travel costs up to $3,500 plus $500 for incidental expenses and all user meeting fees will be provided by Dyalog.

Step 3: Complete Phase I

In Phase I of the competition you will be introduced to APL as you tackle 10 small problems that can each be solved using a single line of APL code.

Step 4: APL Phase II

Things start to heat up in Phase II. Here you will be challenged with a set of problems of varying complexity. You'll code your solutions and upload a file containing the code.

You can choose to answer questions within one, or all, of the following categories:

  • Cryptography
  • Physics
  • Neural Networks

Step 5: Wait for your results!

The winners of the competition will be announced on the competition website on 3 September.
