History
Badger stores the output of every run in a collection of yaml files. You can cd to the Badger archive root and view the historical optimization data. The file structure is a tree-like one, with year, year-month, year-month-day as the first 3 levels of branches, and the optimization runs as leaves:

The yaml data file contains the routine information and the solutions evaluated during the run. The content would look like this:
