Detailed Description

Hides the details of the dictionary matrix implementation. In the future, GLOP will support generating the dictionary one row at a time without having to store the whole matrix in memory.

Constructor & Destructor Documentation

RevisedSimplexDictionary() [1/2]

operations_research::glop::RevisedSimplexDictionary::RevisedSimplexDictionary ( const DenseRow * col_scales, RevisedSimplex * revised_simplex )

inline

RevisedSimplex cannot be passed const because we have to call a non-const method ComputeDictionary.

Todo

(user): Overload this to take RevisedSimplex* alone when the caller would normally pass a nullptr for col_scales so this and ComputeDictionary can take a const& argument.

Definition at line 876 of file revised_simplex.h.

RevisedSimplexDictionary() [2/2]

operations_research::glop::RevisedSimplexDictionary::RevisedSimplexDictionary ( const RevisedSimplexDictionary & )

delete

This type is neither copyable nor movable.
