Then visit http://localhost:8080 in your browser

Command Line

# Basic usage
uv run python recomb.py 3p1s

# With inventory

How It Works

The calculator uses dynamic programming to find optimal crafting recipes:

• Items are processed bottom-up by total mods (p+s)
• Each item stores the top-K cheapest recipes
• Inventory items let you skip steps you've already crafted
• Only the first occurrence of each inventory item is used per recipe

Item Notation

• 1p0s = 1 prefix, 0 suffix
• 2p1s = 2 prefix, 1 suffix
• etc.

Mostly vibecoded with Claude, I'll remake it properly one day.
