The Italian C++ Conference 2019 keynote:
"Allegro" Means Both Fast and Happy. Coincidence?
by Andrei Alexandrescu
About the video:
Sorting and searching. Two fundamental tasks in Computer Science, and definitely among the most studied. Efficient algorithms for sorting and searching are now taught in core undergraduate classes. Are they at their best, or is there more blood to squeeze from that stone? This talk will explore a few less known – but more allegro! – variants of classic algorithms.
