Run ng test to execute the unit tests via Karma.
The code is organized as follows Inside the app folder there are three sub-folders, utils, game-mode and game. Game mode is a template for selecting the number of tiles. Based on this input, the size of the grid will change.
The game folder consists of the A*Star implementation based on the manhattan distance heuristic. Node is the grid which consists of a heuristic.
app.component is the root of the GUI. The tests are written inside utils/utils.spec.ts and game/game.spec.ts

-
You can move the tile in up, dowm, left or right direction. However only when there is an empty cell in the neighbourhood.

A demo data is read in for the auomated mode. In this mode, the A* star algorithm is implemented to automatically reach the goal state. This is tested only with a grid size of 4x4. This can however be adjusted.
- The automated mode can be improved using the A* IDP algorithm.
