C++ Reference: class SequenceVar

Note: This documentation is automatically generated.

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.

Method
Accept	Return type: virtual void Arguments: ModelVisitor* const visitor Accepts the given visitor.
ActiveHorizonRange	Return type: void Arguments: int64_t* const hmin, int64_t* const hmax Returns the minimum start min and the maximum end max of all unranked interval vars in the sequence.
ComputePossibleFirstsAndLasts	Return type: void Arguments: std::vector<int>* const possible_firsts, std::vector<int>* const possible_lasts Computes the set of indices of interval variables that can be ranked first in the set of unranked activities.
ComputeStatistics	Return type: void Arguments: int* const ranked, int* const not_ranked, int* const unperformed Compute statistics on the sequence.
DebugString	Return type: std::string
DurationRange	Return type: void Arguments: int64_t* const dmin, int64_t* const dmax Returns the minimum and maximum duration of combined interval vars in the sequence.
FillSequence	Return type: void Arguments: std::vector<int>* const rank_first, std::vector<int>* const rank_last, std::vector<int>* const unperformed Clears 'rank_first' and 'rank_last', and fills them with the intervals in the order of the ranks. If all variables are ranked, 'rank_first' will contain all variables, and 'rank_last' will contain none. 'unperformed' will contains all such interval variables. 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.
HorizonRange	Return type: void Arguments: int64_t* const hmin, int64_t* const hmax Returns the minimum start min and the maximum end max of all interval vars in the sequence.
Interval	Return type: IntervalVar* Arguments: int index Returns the index_th interval of the sequence.
Next	Return type: IntVar* Arguments: int index Returns the next of the index_th interval of the sequence.
RankFirst	Return type: void Arguments: int index Ranks the index_th interval var first of all unranked interval vars. After that, it will no longer be considered ranked.
RankLast	Return type: void Arguments: int index Ranks the index_th interval var first of all unranked interval vars. After that, it will no longer be considered ranked.
RankNotFirst	Return type: void Arguments: int index Indicates that the index_th interval var will not be ranked first of all currently unranked interval vars.
RankNotLast	Return type: void Arguments: int index Indicates that the index_th interval var will not be ranked first of all currently unranked interval vars.
RankSequence	Return type: void Arguments: const std::vector<int>& rank_first, const std::vector<int>& rank_last, const std::vector<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.
SequenceVar	Arguments: Solver* const s, const std::vector<IntervalVar*>& intervals, const std::vector<IntVar*>& nexts, const std::string& name
~SequenceVar
size	Return type: int64_t Returns the number of interval vars in the sequence.
