Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Ceres Solver's API and documentation assume a deep understanding of nonlinear optimization concepts.
Primary development is in C++, with limited or no direct support for other languages, which can be a barrier for non-C++ developers.
Setting up the environment requires detailed knowledge of build systems like CMake and dependencies management.
The solver's performance is highly dependent on how well the problem is formulated, which can lead to suboptimal results if not carefully tuned.
