This plot represents the number of papers that were submitted to the French speaking conference Algotel’09. The blue plot represents the number of papers submitted before time t, as a function of time in hours, starting at the first submission. We can clearly see two periods in which there was a high number of submissions (around time 75 and time 175): the blue plot rises sharply at these times. They correspond to the submission deadline for the conference, which was first scheduled on a Friday night, then has been rescheduled for the following Thursday (the blue plot still grows slightly after this second deadline, which corresponds to papers on which modifications were performed after the deadline due to technical reasons).
The red (resp. green) plot represents the number of papers that were submitted before time t and have been accepted for presentation at the conference (resp. rejected). First we can see that there is no overwhelming correlation between the time at which papers were submitted and the fact that they were accepted or rejected: there have been acceptances and rejects for all submission times.
However, we observe that the red plot is above the green one most of the time, which means that, among papers submitted early, a higher fraction was accepted (the final acceptance rate was 48%). We can also observe that, for both deadlines, the red plot rises less sharply than the green one, indicating that papers that were submitted just before the deadline tended to be rejected more often than papers submitted some time before it.
