Line Expansion Optimality

Units:	-
Mode:	Input Only
Multi-band:	False
Default Value:	2
Validation Rule:	In (0,2)
Key Property:	No
Description:	Expansion planning integerization scheme.

Line Expansion Optimality controls the integerization of line build decisions in LT Plan. It can take the following values:

Linear (value = 0)

Build decisions are allowed to be linear (faster but can result in partial build/retire outcomes).

Integer (value = 2)

Build decisions are strictly integer (only whole lines can be built).

Note: The option Optimality controls the linear/integer decision at the global level. You can also choose to integerize only part of the horizon using the switch Integerization Horizon. Since the value of Expansion Optimality is Integer by Default, setting the LT Plan Optimality to Linear will always linearize build decisions (even if the Expansion Optimality is set to Linear).
