Initially when I began to read papers on this problem , I found some papers which mentioned algorithms but they were just names and no other details . I found out some papers which mentioned algos like base 3 , base 5 , sphere methods , block algo and KD algo . What I could understand was only base 3 algo and it gave me 0.41 points . I didn't understand a bit of the other algos and therefore couldn't implement them . further I improved by using an exhaustive bad time complexity solution but it couldn't further incorporate the base 3 solution with it . I would like to know what other ideas were implemented by people specially toppers of the problem and also the details if anyone implemented the above algos I have mentioned and how did they take care of time limits if exhaustive algos were involved .
