In this paper. a novel iterative sparse extended information filter (ISEIF) was proposed to solve the simultaneous localization and mapping problem (SLAM). which is very crucial for autonomous vehicles. The proposed algorithm solves the measurement update equations with iterative methods adaptively to reduce linearization errors. https://www.diegojavierfares.com/super-super-Proven-Winners-reg-Fun-And-Games-reg-Eye-Spy-Foamy-Bells-special-save/
