Find optimal armor set for any stat within weight limitations.

requirements

In game, equip your weapon loadout and amulet loadout, and remove all armor.
Take your carry weight max capacity, and multiply it by .299 if you want a light roll, .699 if you want a medium roll, or .999 if you want a heavy roll.
Subtract your current equip load from the result of the step above. The program will later prompt for this number.

cargo run --release; This will cache the Fextralife's wiki pages for helms, armor, gauntlets and greaves. Subsequent runs will use the cache. Delete ~/.cache/fextralife and re-run to get fresh data (only necessary when game updates).
Follow the prompts to choose the stat you want to maximize (enter 0 for physical, 12 for poise, etc).
If you want to ignore specific pieces (if, for example, you can't access those pieces yet), enter them when prompted for "ignore keywords".
When prompted, enter the weight you calculated earlier.
The program will calculate all possible armor sets within your weight limitation, and produce the set with the highest chosen stat within your weight limitation.

Some armor stats on the Fextralife Wiki pages for all components of a particular equipment slot sometimes differ from the actual game data, or the data on a particular component's dedicated page.
This program is only as accurate as the Fextralife Wiki.
Poise only has significant increments in numbers divisible by 41, 45, 51, 53, 58, 69, 75, 101. This program does not care about that.
