# Expired bounty without a good answer?

My bounty is expired on my question: Name of the class of graphs obtained by deleting $\mathcal{Q}_d$ from $\mathcal{Q}_n$ - and I must award it within 24 hours. The only answer was down-voted (not by me), and does not answer the question whatsoever. What should I do in this case? Is there anything I can do besides awarding the bounty anyhow?

2. Has score $2$ or higher.
