com.google.ortools.constraintsolver.SequenceVar Class Reference

Detailed Description

A sequence variable is a variable whose domain is a set of possible
orderings of the interval variables. It allows ordering of tasks. It
has two sets of methods: ComputePossibleFirstsAndLasts(), which
returns the list of interval variables that can be ranked first or
last; and RankFirst/RankNotFirst/RankLast/RankNotLast, which can be
used to create the search decision.

interval()

IntervalVar com.google.ortools.constraintsolver.SequenceVar.interval

(

int

index

)

Returns the index_th interval of the sequence.

Definition at line 113 of file SequenceVar.java.

next()

IntVar com.google.ortools.constraintsolver.SequenceVar.next

(

int

index

rankFirst()

void com.google.ortools.constraintsolver.SequenceVar.rankFirst

(

int

index

)

Ranks the index_th interval var first of all unranked interval
vars. After that, it will no longer be considered ranked.

(

int

index

)

Ranks the index_th interval var first of all unranked interval
vars. After that, it will no longer be considered ranked.

Definition at line 87 of file SequenceVar.java.

rankNotFirst()

void com.google.ortools.constraintsolver.SequenceVar.rankNotFirst

(

int

index

)

Indicates that the index_th interval var will not be ranked first
of all currently unranked interval vars.

rankSequence()

void com.google.ortools.constraintsolver.SequenceVar.rankSequence	(	int[]	rank_first,
		int[]	rank_last,
		int[]	unperformed )

Applies the following sequence of ranks, ranks first, then rank
last. rank_first and rank_last represents different directions.
rank_first[0] corresponds to the first interval of the sequence.
rank_last[0] corresponds to the last interval of the sequence.
All intervals in the unperformed vector will be marked as such.
