Hey Margaret,
This is almost perfect, but for one small error in a place neither of us looked at closely. It took me over an hour to figure it out. As usual it's in the last place you'd look. Take a look at my suggestion and see if you agree.
You have to do something with the return value of bfs.
| q = [] | ||
| cur = index | ||
| q << cur | ||
|
|

I would add the starting point of this BFS' color to compat and then use compat[elem] throughout instead of static colors.
| end | ||
| compat = {} | ||
| dislikes.each_with_index do |neighbors, index| | ||
| bfs(dislikes, compat, index) |

You are actually not doing anything with the return value for bfs. So... maybe:
Suggested change
| bfs(dislikes, compat, index) | |
| unless bfs(dislikes, compat, index) | |
| return false | |
| end |
| q << elem | ||
| end | ||
| end | ||
| end |

Hi Chris, I'm trying to do with with the color method and BFS but it's not working. Can you take a look and leave some comments? Thanks
