Abstract
This paper explains a subtle issue in the martingale analysis of the IMM algorithm, a state-of-the-art influence maximization algorithm. Two workarounds are proposed to fix the issue, both requiring minor changes on the algorithm and incurring a slight penalty on the running time of the algorithm.

Notes
- 1.
The original paper has a typo here. It says to reset \(\ell \) to \(\ell (1+\log 2/\log n)\), but this is not necessary. Only resetting \(\ell \) to \(\ell + \log 2/ \log n\) is enough.
