Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
GTSAM is primarily a C++ library, which can be challenging for developers without strong C++ skills.
While there are bindings and wrappers available for other languages like Python, they may not cover all functionalities or might lag behind the primary C++ library in terms of updates.
Setting up GTSAM can be complex due to dependencies and configuration requirements for nonlinear optimization tasks, especially on different operating systems.
GTSAM's performance may degrade when dealing with extremely large datasets or highly complex factor graphs, leading to increased computational time and resource usage.
