instanceNodes :: List -> Instance -> (Ndx, Ndx, Node, Node)Source

setInstanceLocationScoreSource

Arguments

:: Instance

the original instance

-> Node

the primary node of the instance

-> Node

the secondary node of the instance

-> Instance

the instance with the location score updated

Sets the location score of an instance, given its primary and secondary node.

applyMoveExSource

Arguments

:: Bool

whether to ignore soft errors

-> List 
-> Instance 
-> IMove 
-> OpResult (List, Instance, Ndx, Ndx) 

Applies an instance move to a given node list and instance.

move :: (List, List) -> (Idx, IMove) -> OpResult (List, List)Source

Apply a move to an instance, ignoring soft errors. This is a variant of `applyMoveEx True` suitable for folding.
