Researchers have devised multiple strategies for an artificial intelligence (AI) agent to solve a random puzzle like Minesweeper.
For decades, attempts at solving games have been unique in solving two-player games (ie, games such as checkers, chess, etc.), where game outcomes can be accurately and efficiently assessed using some artificial intelligence (AI). ) Search technology and collecting huge amounts of gameplay stats. However, such methods and techniques do not apply directly to the puzzle-solving domain, as puzzles are usually played alone (single player) and have special features (such as random or hidden information). So, the question arises as to how the AI technique can retain its functionality to solve two-player games, but instead apply the same agent to the puzzle?
Over the years, puzzles and games have been considered interchangeable or interchangeable. In fact, it may not be all the time. From a real-world perspective, ‘play’ is something we encounter every day; Dealing with strangers. For example, not making the right decision (i.e., getting married) or making the wrong decision (i.e., quitting the job) or not making the right decision (i.e., remorse for ‘what if’). Meanwhile, the ‘puzzle’ is known to be there, and something that has not yet come out is also hidden. One such known context is, for example, the discovery of ‘amazing’ material
The researchers adopted an AI agent with two science-based strategies and two data-based strategies to make the best use of the known and unknown information of the current decision to better evaluate the next decision. As a result, a single-agent can establish a boundary between puzzle-solving and game-playing pattern for random puzzle Minesweeper.
The boundary between the known and the unknown is usually blurred and such a situation plays a particularly important role in real-world problems that are very difficult to identify. As Professor Iida commented: “With the AI agent’s ability to improve puzzle solving performance, the boundaries of solvability are clearly visible. Assessing the level of risk and so on. In essence, we all live within ourselves Minesweeper The world is trying to figure out a way forward for us, avoiding the ‘bomb’ in our lives.
There are many uncertainties with the face-paced advancement of existing technology and new models of computing available (i.e. IoT, cloud-based services, EDGE computing, neuromorphic computing, etc.). This situation may be true of individuals (i.e., affordability of technology), community (i.e., acceptance of technology), society (i.e., culture and standard) and national levels (i.e., changes in policy and rules). “Every day human activity involves a lot of ‘game’ and ‘puzzle’ situations. However, mapping the solvability pattern on a scale can create boundaries between the known and the unknown, reducing the risk of the unknown and increasing the usefulness of the known,” said Ms. Chang, lead author of the study. Liu explains: “Such a feat is achieved by keeping the puzzle fun and challenging with knowledge – driven techniques, AI technology and measurable uncertainty (winner rate, success rate, progress rate, etc.).”

Ms. Chang Liu is a doctoral student at the School of Advanced Science and Technology (JAIST), Nomi, Japan. Her research focuses on researching appeal information about the evolution of puzzle games based on game mechanics and player experience, overseen by Professor Hiroyuki Ida in the Lab of Entertainment Technology. She analyzes important factors in the evolution of ancient puzzle games from ancient times and solves puzzles to find the line between puzzles and games and analyzes information in the process of playing games.
