A problem on DoTA hero pool.

Revision en3, by Yuki726, 2019-05-15 13:42:18

There are approximately 35 mid heroes in dota 2. You are given a matrix winprob[35][35], where winprob[i][j] denotes the probability of ith hero winning against jth hero in midlane (matrix is derived from previously played games).
Problem : What's the minimum cardinal subset of heroes (to learn) such that when the opponent picks a mid hero, we can always pick a hero from our subset and get the probability of winning atleast (60%).

I can only think of bruteforce. Is there any better algorithm?
