Yes.
If an individual or organization has a solution that applies to challenges running at the same time, or at different times, and the solution is clearly applicable, then we would encourage submitting that solution again. To qualify for a contract award to a given challenge topic, a company must submit their solution to that challenge. AFWERX Challenge will not accept a prior submission as the qualifying action for a new topic. This is due to the fact that challenge submission forms may change topic by topic and that the review process is triggered by the topic submission.
That said, the same solution submitted by the same submitter should be materially different in that it clearly addresses each challenge topic individually.
