CLI Usage

The Command-Line Interface (CLI) is a powerful way to interact with the application, allowing you to calculate shortest paths, manage datasets, and customize settings.

Starting the CLI

Once the macLinuxProjectBuilder.sh or windowsProjectBuilder.bat script completes, the terminal will display the following prompt:

Enter a command or the start node:

This indicates that the program is ready to accept commands or input for shortest path calculations.

Basic Commands

Node IDs

• Enter a start node (integer between 1 and 23,947,347), and the program will prompt for an end node.

• The shortest path between the nodes will be calculated and displayed.

• Example:

  Enter a command or the start node: 1
  Enter the end node: 5
  Shortest path: [1 -> 3 -> 5]
  Distance: 12.5

Commands

• Enter keywords to perform specific actions. For example:

  • help: Lists all available commands.

    Available commands:
    - fast
    - med
    - comparator
    - display files
    - exit

  • build graph: Rebuilds the graph structure from the dataset.

Advanced Commands

comparator

• Activates "Comparator Mode," which compares results from A* and Dijkstra for the same path.

• Example:

  Enter a command or the start node: comparator
  Comparator mode activated.
  Enter a start node: 1
  Enter an end node: 10
  A*: Distance = 20.3, Time = 1.2ms
  Dijkstra: Distance = 20.3, Time = 1.8ms

weight

• Prompts for a new heuristic weight for A*.

• Example:

  Enter a command or the start node: weight
  Enter new weight: 1.5
  Heuristic weight updated.

build lm

• Rebuilds landmarks for improved pathfinding performance.

---

Exiting the CLI

• Type exit to terminate the application.

• The API server (if running) will also stop.

• Example:

  Enter a command or the start node: stop
  Application terminated.
