Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Steep learning curve due to complex factor graph concepts

   Understanding and implementing factor graphs requires significant expertise in optimization theory and robotics

2. 02

   Limited language support, primarily C++

   Lack of native bindings for other languages like Python or Java can limit accessibility to non-C++ developers

3. 03

   Documentation is sparse and not beginner-friendly

   Official documentation assumes a high level of familiarity with the underlying mathematics and robotics concepts

4. 04

   Performance can degrade for very large-scale problems

   Optimization algorithms may become computationally expensive as problem size increases, leading to slower execution times

What it does well

• Factor graph-based optimization for solving least-square problems

• Supports a wide range of robotics and computer vision tasks

• Highly optimized algorithms for efficient computation
