Simultanous Localistion and Mapping (SLAM) is a process used by robots and d autonous systems to build a map of an unknown environmentat while an guaranousy determinang their ir position with it. A key contesent of many SLAM algorytms is pose graph optimization, which involves matematical techniques to rephe these estimated positions and orientations of thee robot and estimativenes in thee environment.

Pose Graph Referention

A pose graph is a mathetical model where nodes deitt robot pozes at different times, and edges deitt spatilal condictions between these poses. These limits are derived frem sensor measurements, such as odometriy or sensor observations of landmarks.

Te goale of pose graph optimization is to find thee set of pozes that best consiglify all conditints. This is formulated as a nonlinear leaset squares problem:

Optimization Techniques

Common methods to solve this problem include iterative algorytms such as Gauss- Newton and Levenberg- Marquardt. These algorytthms linearize the nonlinear problem around an initiats and iteratively rephe the solution.

Graph- based solvers often utilize sparsie matrix techniques to o efficiently handle large-scale problems, enabling real- time performance in robotic applications.
