Simulate Walker with Dynamic Grid Broadcasting — simulate_walker

Simulates a single walker with real-time grid synchronization via nanonext pub/sub pattern. Workers receive broadcasts of new black pixels, enabling realistic walker interactions.

Usage

simulate_walker_dynamic(
  walker_id,
  initial_grid,
  pub_socket = NULL,
  sub_socket,
  grid_size,
  neighborhood = "4-hood",
  boundary = "terminate",
  max_steps = 10000L
)

Arguments

walker_id: Integer. Unique walker identifier.
initial_grid: Matrix. Initial grid state.
pub_socket: Publisher socket for broadcasting updates (optional). If NULL, worker returns results without broadcasting (main process broadcasts).
sub_socket: Subscriber socket for receiving updates.
grid_size: Integer. Grid dimensions (n x n).
neighborhood: Character. "4-hood" or "8-hood".
boundary: Character. "terminate" or "wrap".
max_steps: Integer. Maximum steps before forced termination.

Value

List with walker results:

walker_id: Walker ID
status: Termination reason
steps: Steps taken
position: Final position
path: List of positions visited
black_pixel_created: Logical. TRUE if created black pixel
