The APL Challenge
Prizes and Eligibility
The APL Challenge is a quarterly event during which you can use APL to solve up to ten problems. It is aimed at newcomers to APL, although anyone is welcome to enter.
For each round, three prizes of USD 100 will be awarded, with chances of winning increasing based on the number of correct entries submitted.
Rounds begin in February, May, August, and November, and last for three months. Winners are announced within three weeks of the end of a round.
Anyone can win a prize except Dyalog employees and associates.
