Abstract 

Abstract: 

LZ-End is a variant of the LZ77 compression algorithm which allows random access to the compressed data. In this paper, we show how the random-access capability of LZ-End allows random edits to the compressed data, which is the first algorithm to randomly edit strings compressed by a Lempel-Ziv algorithm.

Thanks for the talk. Your approach embedding yourself into the slide presentation looks very sophisticated (and maybe complicated?).
Nevertheless, I've a small question regarding the upper bound on the edit on the LZ-End parsing with a sliding window:
I think that you meant $l$ to be the length of the decoded string within the sliding window where the edit took place.
Otherwise, if $l$ is the entire string length, then there is no dependency on the sliding window size.
