🎮 Evony Card Compose Optimizer

Live: https://sefi-roee.github.io/evony/

A sophisticated web application for optimizing card composing strategies in Evony's Lucky Composing event.

Features:

• Input your card inventory (Green, Blue, Purple, Orange, Red cards)
• Assign custom rankings to Lucky Box outcomes (I-X)
• Get optimal compose recommendations using advanced algorithms
• View results with interactive charts showing residual cards
• Uses LP relaxation + extensive local search for near-optimal solutions

Technology Stack:

• Pure JavaScript (no build tools required)
• Bootstrap 5 for responsive UI
• Chart.js for data visualization
• javascript-lp-solver for linear programming
• Custom local search algorithms (1-for-1, 1-for-2, 2-for-2 swaps)

How to Use:

1. Enter your card counts
2. Assign rankings to each Lucky Box outcome (higher = more valuable)
3. Click "Optimize Composes!"
4. See which recipes to use and how many cards will remain

🎁 Civilization Treasure Chest Calculator

Live: https://sefi-roee.github.io/evony/civilization-treasure/

Calculator for chest count planning when each chest randomly gives 1 of 7 civilization tokens.

Features:

• Set token targets for each civilization (Y1..Y7)
• Set required success probability (X)
• Solver mode toggle: Auto, Exact only, or Fast approximation only
• Runtime safety warnings for very large inputs

🎯 Gen Scrolls Calculator

Live: https://sefi-roee.github.io/evony/gen-scrolls/

Calculator for planning repeated scroll attempts with an exact binomial success model.

Features:

• Enter the per-scroll success probability
• Set the target number of successes you want to reach
• View exact winning probability for any repetition count
• Use linked sliders to move between win probability and needed repetitions
• See the exact binomial formula rendered with the live input values
• Inspect a probability-vs-attempts curve with the current point highlighted
