APL Problem Solving Competition

The APL Problem Solving Competition was a yearly contest hosted by Dyalog Ltd. During the Dyalog user meeting that followed shortly after the competition closed, the winners were announced, followed by presentations by the grand prize winner and the professional prize winner. In 2024, the competition was replaced by the new APL Challenge.

The APL Quest is a series of chat events and follow-up videos addressing the Phase 1 problems of past years.
