APL Problem Solving Competition

Dyalog Ltd is pleased to host the APL Problem Solving Competition. The challenge has two phases:

  • Phase I consists of ten simple problems that must all be solved.
  • Phase II consists of more complex problems in three categories.

We encourage students at all levels of education, anywhere in the world, to participate. Non-students are welcome to submit solutions and may receive an honourable mention, but proof of enrolment in a full-time educational program is required to win a cash prize.

Thanks to our sponsors Fiserv and SimCorp, substantial cash prizes are offered. In addition, the winner is invited to the next Dyalog user meeting to present their winning work.
