operations_research::FilterModelView Class Reference

Detailed Description

A lightweight sub-model view that uses boolean vectors to enable or disable specific items. Iterating over all active columns or rows is less efficient, particularly when only a small subset is active.

Note

this view does not store any size-related information.
