I think you won't be satisfied until you can solve these by hand (I'm the same way)
Localization or localisation may refer to: Localization of function, locating psychological functions in the brain or nervous system; see Linguistic intelligence This example demonstrates how to implement the Simultaneous Localization And Mapping (SLAM) algorithm on a collected series of lidar scans using pose graph optimization . In order to draw conclusions on the performance of the tested techniques, the experimental results were collected under the same conditions EKF-SLAM: Landmark-based SLAM using the Extended Klaman Filter Cyrill Stachniss, Fall2020 .
