1. What is EVPI in League of Legends?

EVPI (Expected Value of Perfect Information) is a decision analysis concept used in League of Legends to quantify the value of having complete information about game states and outcomes before making strategic decisions.

2. How Does the Calculator Work?

The calculator uses the EVPI formula:

Where:

• \( EVwPI \) — Expected Value with Perfect Information
• \( EVwoPI \) — Expected Value without Perfect Information

Explanation: EVPI represents the maximum amount a player should be willing to pay for perfect information about game outcomes before making a decision.

3. Importance of EVPI Calculation

Details: Calculating EVPI helps League of Legends players and analysts determine the value of scouting, vision control, and information gathering in competitive gameplay decisions.

4. Using the Calculator

Tips: Enter the expected value with perfect information and expected value without perfect information. Both values should be non-negative numbers representing decision outcomes.
