Questions and Answers

What is the purpose of the flag in the self-stabilizing distance-2 coloring algorithm?

  • To detect conflicts with neighboring nodes
  • To indicate the termination of the recoloring process
  • To request recoloring from neighboring nodes (correct)
  • To indicate the color of the node

    • What is the condition for starting the recoloring process?

  • When the node's degree is greater than its color
  • When all neighbors have completed their recoloring process
  • When the node's color is invalid or too large
  • When all neighbors have acknowledged the recoloring request (correct)

    • What happens when a node's color is invalid or too large?

  • The node changes its color to a random value
  • The node terminates the algorithm
  • The node requests recoloring from its neighbors (correct)
  • The node notifies its neighbors of the conflict

    • What is the purpose of the NextColor function?
