Search Trees Best-case Complexity 3.1 BSTs O(1) O(1) O(1) 3.2 2 ­3 Trees O(1) O(1) O(1) Memory Model  ­ All memory accesses are O(1) time  ­ In reality, this is not always the case Limitations  ­ Ideally, we like all the data to be in CPU registers, but it is not likely because the registers are relatively small.  ­ Moreover, we want to keep the data as close to the CPU as possible, because differences in access times can be extreme. Eg. Compare 101 to 103 to 107 3 Terminology • Temporal Locality  Programs access a small subset of data over and over  Eg: Likely to have b in the future b a c • Spatial Locality  If a program access a memory location, it is very likely to access its neighbors  Eg: Likely to access item near b a b c...
