I have recently submitted a paper to a top notch conference. Only then, I have realized that another good conference has announced a call for papers recently.
My problem is that the notification deadline for the first conference is after the submission deadline of the second one. Given the chances of acceptance, my best course would be to withdraw the submitted paper, and then submit it to the second conference. However, I do not want to just withdraw the paper. I would rather send an email to the committee, stating the reason, and apologizing for the inconvenience.
My question is, which committee (among general co-chairs, technical co-chairs, advisory committee, steering committee etc.) should I send the email, and roughly what should I write so that this situation gets less cringey for everyone?
