PPT-Tight Bounds for Graph Problems in Insertion Streams

Xiaoming Sun and David P Woodruff Chinese Academy of Sciences and IBM Research Almaden Streaming Models Long sequence of items appear onebyone numbers points edges usually adversarially. Our result is modular 1 We describe a carefullychosen dynamic version of set disjointness the multiphase problem and conjecture that it requires 84861 time per operation All our lower bounds follow by easy reduction 2 We reduce 3SUM to the multipha Why use laziness. Laziness has lots of interesting uses. Build cyclic structures. Finite representations of infinite data.. Do less work, compute only those values demanded by the final result.. Build infinite intermediate data structures and actually materialize only those parts of the structure of interest.. Masaru . Kamada. Tokyo . University of . Science.
