Splitting |
|
|
- Margin: Margin(MBR(Group 1)) + Margin(MBR(Group 2))
|
|
- Overlap: Volume(MBR(Group 1) MBR(Group 2))
|
|
|
- For each axis, sort entries by low values
|
|
- Enumerate possible groupings or distributions
|
|
- kth distribution: First entries and rest
|
|
- Compute sum of margins along that axis of all distributions
|
|
- Do the same by sorting high values of each axis
|
|
- Choose axis with least sum of margin values
|
|
|
- For chosen axis and low/high value, choose distribution with least overlap
