Despite consistently yielding the best compression on repetitive text collections, the Lempel-
Ziv parsing has resisted all attempts at offering relevant guarantees on the cost to access an …

We study the complexity of constructing an optimal parsing φ of a string s= s 1⋯ sn under the
constraint that given a position p in the original text, and the LZ76 (also known as LZ77 or …
