Two-Stage Column Generation Optimization Algorithm for Flight Strings based on Deep Reinforcement Learning

Abstract: Existing algorithms for the flight string scheduling problem often fall short due to their NP-hard nature and difficulties with local optima. To enhance efficiency, we propose a two-stage ...

A Hybrid Algorithm for Loop Closure Detection in LiDAR SLAM Using Global Point Cloud Density and Local Triangular Features

Abstract: In Simultaneous Localization and Mapping (SLAM) systems, LiDAR odometry inevitably accumulates drift in pose estimates, leading to significant trajectory deviations and inconsistencies in ...
