Thanks a lot for sharing.

Hi There,

Good Day!

Most conferences specifically forbid this practice. There will be a notation in the Call for Papers about work not having appeared previously and not being submitted simultaneously elsewhere.

If you are thinking of submitting two places, then withdrawing the submission from one if the paper is accepted at the other -- don't. When people realize you've done this, they will be reluctant in the future about spending time reviewing or championing your paper, because it might get withdrawn after they've put in the work.

So it is advisable to avoid such practice.

Thanks!!!
