The Suzuki-Abe algorithm is a computational method used in the field of computational geometry and robotics, particularly for solving the **motion planning problem** in high-dimensional spaces. Developed by researchers Hiroshi Suzuki and Toshiyuki Abe in the late 1990s, the algorithm is designed to efficiently navigate a robot or object through an environment with obstacles while avoiding collisions.

The core idea behind the Suzuki-Abe algorithm is to approximate the **visibility graph** of a workspace, which represents the connections between free-space regions that are mutually visible. Unlike traditional methods that rely on exact geometric computations, the Suzuki-Abe algorithm employs probabilistic roadmaps (PRMs) or sampling-based techniques to reduce complexity. It focuses on generating a graph where nodes represent sampled configurations of the robot, and edges represent feasible paths between them, ensuring collision-free motion.

One of the key advantages of the Suzuki-Abe algorithm is its ability to handle **non-convex and cluttered environments** more effectively than grid-based or cell decomposition methods. By leveraging probabilistic sampling, it balances computational efficiency with path accuracy, making it suitable for complex scenarios where exact geometric computations would be computationally expensive.

The algorithm has applications in robotics, including autonomous navigation, industrial automation, and medical robotics. It is particularly useful in scenarios where real-time path planning is required, such as in search-and-rescue missions or manufacturing processes involving intricate workflows.

While the Suzuki-Abe algorithm is effective, it is not without limitations. Like other sampling-based methods, it may occasionally produce suboptimal paths or fail to find solutions in highly constrained environments. However, refinements and hybrid approaches combining it with other techniques have helped mitigate these issues over time. Its contributions to motion planning remain significant in both academic research and practical engineering applications.
