Generalized Whac-a-Mole
We consider online competitive algorithms for the problem of collecting weighted items froma dynamic set S, when items are added to or deleted from S over time. The objective isto maximize the total weight of collected items. We study the general version, as well asvariants with various restrictions, including the following: the uniform case, when all itemshave the same weight, ...
متن کاملThe stoichiometric divisome: a hypothesis
Dividing Escherichia coli cells simultaneously constrict the inner membrane, peptidoglycan layer, and outer membrane to synthesize the new poles of the daughter cells. For this, more than 30 proteins localize to mid-cell where they form a large, ring-like assembly, the divisome, facilitating division. Although the precise function of most divisome proteins is unknown, it became apparent in rece...
