Description

Classic 2048 puzzle game redefined by AI.
Our 2048 is one of its own kind in the market. We leverage multiple algorithms to create an AI for the classic 2048 puzzle game.
* Redefined by AI *
We created an AI that takes advantage of multiple state-of-the-art algorithms, including Monte Carlo Tree Search (MCTS) [a], Expectimax [b], Iterative Deepening Depth-First Search (IDDFS) [c] and Reinforcement Learning [d].
(a) Monte Carlo Tree Search (MCTS) is a heuristic search algorithm introduced in 2006 for computer Go, and has been used in other games like chess, and of course this 2048 game. Monte Carlo Tree Search Algorithm chooses the best possible move from the current state of game's tree (similar to IDDFS).
(b) Expectimax search is a variation of the minimax algorithm, with addition of "chance" nodes in the search tree. This technique is commonly used in games with undeterministic behavior, such as Minesweeper (random mine location), Pacman (random ghost move) and this 2048 game (random tile spawn position and its number value).
(c)Iterative Deepening depth-first search (IDDFS) is a search strategy in which a depth-limited version of DFS is run repeatedly with increasing depth limits. IDDFS is optimal like breadth-first search (BFS), but uses much less memory. This 2048 AI implementation assigns various heuristic scores (or penalties) on multiple features (e.g. empty cell count) to compute the optimal next move.
(d) Reinforcement learning is the training of ML models to yield an action (or decision) in an environment in order to maximize cumulative reward. This 2048 RL implementation has no hard-coded intelligence (i.e. no heuristic score based on human understanding of the game). There is no knowledge about what makes a good move, and the AI agent "figures it out" on its own as we train the model.

Trop de pub partout

Zlitus on

France

Je ne suis pas contre la pub en général, mais la y'en a beaucoup trop (video plein écran qui se lance pendant la partie, bannière de pub sous la partie, pub au lancement de l'application, etc, etc). J'ai désinstallé.

Cool

Good App but too many ads

Comment of January 6th, 2023: The main change brought by version 5.6 of January 4th, 2023, is that there are now even more ads than before, even _during_ the games! Very bad strategy of the developer, since the users will now play less, or do it in plane mode. ==> His income will actually drop. :-( ---- Comment of January 11th, 2023, about version 5.7: The developer wrote: > I have recently reduced ad frequency Good to hear, thanks! However, I still see ads before _and_ during the games. In my humble opinion, you should avoid during, as this spoils all fun. Before is already (more than) enough...
