Reinforcement Learning for Mobile Games

Reinforcement Learning for Mobile Games

With an estimated 2 billion gamers in the entire world, it’s inevitable that the gaming industry has turned to advanced approaches to improve its offering. One of the many ways that this has been done is through deep reinforcement learning game techniques. This is done through the incorporation of machine learning and other key strategies to improve gaming as much as possible. But, what is reinforcement learning? And how does it improve anything? Keep reading to learn more about this innovative machine learning technique.

What is Reinforcement Learning?

First things first, you should have a basic understanding of what is meant by reinforcement learning. Simply put, this is an area of machine learning that’s taking the technology world by storm. If your aim is to maximize rewards in any situation, then this is the most suitable action that you can take. There are various machines and software systems that should help you to achieve your aim. These are essential for ensuring that the best path is found to allow for the most suitable action to be taken.

This is quite different from supervised learning. In this case, you’re mainly dealing with training data that should coincide with the model to provide you with the correct answer. On the contrary, reinforcement learning doesn’t look for a correct answer. Instead, have a reinforcement agent who dictates what needs to be done to perform a specific task. So, if you don’t have any training data, it’s still possible to learn from experience to ensure that a path is made available to achieve the end goal.

Reinforcement learning has been used in mobile games by leading app developers and has been giving successful results in increasing entertainment and engagement levels in games.

The following are some of the main points that you should expect when you’re dealing with reinforcement learning:

  • Input. This is where your model will be able to start. The input is essentially the initial stage of the entire process.
  • Output. There are various potential outputs since there’s more than one solution to each problem.
  • The model. This is what your software systems use to continue to learn different potential solutions.
  • Training. This is based on the input given to the model. Depending on the result, as a user, you can choose to punish or reward your model based on what is your output.
  • Solution. This is dependent on the maximum reward given by the model.

Before you can go deeper into the examples and algorithms of reinforcement learning, you should know that there are different types of reinforcement learning. These can be summarized as follows.


This type of reinforcement happens when a particular situation has a positive effect on behavior. Thus, it can either maximize performance, sustain long-term change, or balance results.


On the other hand, reinforcement learning can be negative. However, this isn’t a bad thing since what this type of reinforcement learning does is to avoid or stop a negative condition. Essentially, you can say that it strengthens behavior. In fact, when you have this reinforcement on games, it helps to provide defiance for subpar performance. This way you can assess what the minimum standard of performance is.

Reinforcement Learning Example

Now that you have an idea of what reinforcement learning is, you should learn more about its real-life application. Since it’s a subset of AI, it’s safe to say that it forms a bulk of many applications nowadays. For instance, reinforcement learning for games has become a popular part of game testing. Game developers are increasingly relying on scripted bots as well as human testers to find bugs in games.

The fact of the matter is that a reinforcement learning game tutorial is a more reliable way for game developers to master extremely complex games. As a result, it has become an innovative way for companies to use reinforcement learning and a variety of machine learning strategies to improve game development. In fact, a robust reinforcement learning game technique should be useful not only create solution-based game environments but to also understand the complexity of the game levels better.

Besides reinforcement learning game playing, it can be useful in the following applications as well:

  • Healthcare
  • Natural language processing
  • Trading and finance
  • Industry automation
  • Engineering

Reinforcement Learning Algorithms

The most crucial aspect of reinforcement learning for games or any other application lies in the reinforcement learning algorithms that you have set. These algorithms should be goal-orientated. The main idea behind them is that they should know how to achieve complex goals. Most importantly, they should know how to maximize rewards. For instance, if you’re focusing on reinforcement learning for games, you should find a way to maximize the rewards won by your players over the many moves that it takes them to reach the end goal.

This is why your reinforcement learning algorithms should mirror human actions by a margin. This means that their actions have to correlate with delayed outcomes. In a way, they should wait and see the results that they produce so that they remain confused by the outcome even if they’ve taken a specific action. The key to developing reinforcement learning algorithms that meet your goals lies in how you implement them. Currently, these are the three main approaches that you can take to ensure that you implement adequate algorithms for your application.

  1. Model-based. This is when you should create a virtual model for your environment that an agent learns to perform in.
  2. Policy-based. This is when you implement policies in each model to ensure that each action is performed in accordance with a reward. It can be a determining reward or one based on probability.
  3. Value-based. Your main goal should be to increase the agent’s value function. Your policy-based algorithm should provide a long-term return.

In summary, if your aim is to improve the overall functionality of your application, then it’s crucial for you to include reinforcement learning techniques. It’s evident that there have been many benefits of reinforcement learning on games in recent times. When you understand the approaches and how reinforcement learning algorithms should be implemented, then it should be easier to interpret the user environment with the aim of obtaining the desired rewards when specific actions are taken.
