Enum VarSelection
This determines the formula used to calculate the estimate of each integer variable, and thus which integer variable is selected to be branched on at a given node. The variable selected to be branched on is the one with the maximum estimate.

Fields
| Name | Description |
|---|---|
| Automatic | Determined automatically. |
| DownOnly | The 'down' pseudo cost. |
| MaxOfUpAndDown | The maximum of the 'up' and 'down' pseudo costs. |
| MaxOfUpAndDownWithMin | The maximum of the 'up' and 'down' pseudo costs, plus twice the minimum of the 'up' and 'down' pseudo costs. |
| MinOfUpAndDown | The minimum of the 'up' and 'down' pseudo costs. |
| ProductOfUpAndDown | The product of the 'up' and 'down' pseudo costs. |
| UpOnly | The 'up' pseudo cost. |
| UpPlusDown | The 'up' pseudo cost plus the 'down' pseudo cost. |
| WeightedFractional | A weighted combination of the 'up' and 'down' pseudo costs, where the weights depend on how fractional the variable is. |
