A PriorityQueue is a list that always keeps its items sorted based on some rule, like smallest to largest. So, when you take an item out, you always get the one with the highest (or lowest) priority.

Progressive Gaussian approximate filter (PGAF) provides an efficient way for estimating the states of nonlinear systems with large prior errors and accurate measurements. However, its performance ...

Future flying ad-hoc networks (FANETs) need to address issues related to delay and channel interference while ensuring high data transmission accuracy. In this letter, we propose a proximal policy ...
