Gian Merlino ebf890fe79 Update master version to 0.9.2-SNAPSHOT. (#3133) 2016-06-13 13:10:38 -07:00
Xavier Léauté e79284da59 new interval based cost function (#2972) 
* new interval based cost function

Addresses issues with balancing of segments in the existing cost function
- `gapPenalty` led to clusters of segments ~30 days apart
- `recencyPenalty` caused imbalance among recent segments
- size-based cost could be skewed by compression

New cost function is purely based on segment intervals:
- assumes each time-slice of a partition is a constant cost
- cost is additive, i.e. cost(A, B union C) = cost(A, B) + cost(A, C)
- cost decays exponentially based on distance between time-slices

* comments and formatting

* add more comments to explain the calculation
