2. TreeMap

 http://www.openslam.org/treemap.html

Treemap is an algorithm for feature based Gaussian SLAM. Actually it is an algorithm for incremental probabilistic inference in a high dimensional Gaussian defined as the product of many low dimensional Gaussians (incremental least square). Treemap can handle different variants of SLAM. Everything, that's specific to a SLAM variant or even to SLAM as a problem is contained in a small driver layer that can be adapted by the user.

3. TORO

http://www.openslam.org/toro.html

TORO is an optimization approach for constraint-network. It provides an efficient, gradient descent-based error minimization procedure. There is a 2D and a 3D version of TORO available.

5. iSAM and iSAM2

iSAM is a general optimization library for incremental sparse nonlinear problems as encountered in simultaneous localization and mapping (SLAM).

6. Sparse Pose Ajustment

7. g2o

http://www.openslam.org/g2o.html

g2o is an open-source C++ framework for optimizing graph-based nonlinear error functions. g2o has been designed to be easily extensible to a wide range of problems and a new problem typically can be specified in a few lines of code. The current implementation provides solutions to several variants of SLAM and BA.

8. Vertigo

http://www.tu-chemnitz.de/etit/proaut/forschung/robustSLAM.html.en

Vertigo is a C++ extension for g2o and gtam. It provides an implementation of switchable constraints and enables g2o and gtsam to solve pose graph SLAM problems despite the presence of false positive loop closure constraints.
