Discussion of Problem 1305. Convex Hull

Not cellular solution
Posted by pmartynov 5 Apr 2014 20:33
Hey guys, I ACed with a cellular automata (a grid of 1000x1000 and a set of rules to transform 0s -> 1s).
But is there any other(faster?) way to find a 45 convex hull given a set of points without a cellular automata?
