Knowledge Representation — Probability Distribution

An AI agent that hunts a player using a live discrete probability distribution over grid cells

Vision Range

14 cells

Max cells the AI can see in its cone

Vision Arc

45°

Total width of the view cone in degrees

Rotation Speed

0.50

Lerp factor toward target angle per tick

AI Moves Every

1 tick

Ticks between AI position updates

Spread Rate

0.35

Fraction of P diffusing to neighbours/tick

Decay Rate

0.000

Mix rate toward uniform per tick (forgetting)

Probability Floor

0.0000

P added to all unobserved cells each tick

Tick Rate

5.0/s

Simulation steps per second

Near-Field Box

3×3

Box of cells always visible around the AI

Spread Rate — how fast uncertainty propagates outward. Higher = player could move farther per tick.

Decay Rate — how quickly the AI "forgets" old certainty, mixing the distribution toward uniform.

Prob. Floor — a persistent small probability added to every unobserved cell, representing background uncertainty.

Yellow cells show the AI's line-of-sight within its cone. Empty visible cells drop to zero probability.

Vision Arc — narrow cone = AI must sweep more carefully; wide cone = fewer hidden areas.

Rotation Speed — lower values show the AI gradually sweeping toward suspected locations.
