Flocking VI

Purpose

This fork is primarily used for logging of the Fiedler eigenvalue and degree (number of connected components) over time. Since it logs this every iteration, usage may be slower than in other examples. For better performance, see Flocking V.

Parameters:

There are two basic types of parameters used: initial conditions and agent parameters. Agent parameters can be updated any time, including while in play. Initial conditions however require a reset before they take effect.

Note: If an initial condition is changed then the Reset button will turn yellow, indicating that a reset is required before some changes take effect.

Initial Conditions:

• Agents: The number of agents to simulate
• Sparsity: The spacing between agents at start, where higher numbers correspond to the agents being spaced further apart.
• Distribution: The distribution between Group 1 and Group 2 agents. Agents from the second group are rendered as the larger dots.
• Metric: The metric type used for the respective group for their zones of attraction. The two options are:
• distance: The agent uses a zone of attraction, specified by the radius
• knn: The agent uses the k nearest neighbors outside of the zone of orientation for their attraction vector.

Agent Parameters:

• Zr: The radius of the zone of repulsion
• Zo: The radius of the zone of orientation
• Za: The radius of the zone of attraction (distance metric only)
• k: The number of neighbors outside of the zone of orientation to use for the attraction vector (knn metric only)
• s: The speed, or the distance per iteration an individual agent travels
• θ: The turn rate (between [0, 180]) where the agent can not adjust their direction vector greater than this number for an individual iteration

Color Key:

• Black: point is not being influenced by any other points (no points in any zones)
• Red: point is being repulsed (contains points in its zone of repulsion)
• Blue: point is being influenced by attraction forces only (contains points only in its zone of attraction)
• Magenta: point is being influenced by orientation forces only (contains points only in its zone of orientation)
• Turquoise: point is being influenced by both attraction and orientation forces (cointains points in both its zone of attraction and zone of orientation)

Controls:

• Use the Play button to start animation
• Use the Pause button to stop animation
• Use the Next button to do one time step of the algorithm.
• Clicking a point toggles display of its zone radii.
• While paused, points can also be dragged around and positioned.
