data structure and algorith:This journey is not just about coding but also about developing problem-solving thinking, optimizing solutions, and building a strong foundation for coding interviews and ...

Abstract: Many studies have been conducted on Dijkstra Algorithm, and one of the implementations of those studies includes vehicle path selection or routing. A traditional Dijkstra Algorithm can ...

ABSTRACT: Nowadays, the development of “smart cities” with a high level of quality of life is becoming a prior challenge to be addressed. In this paper, promoting the model shift in railway ...

本文使用 Python 实现了 Dijkstra 算法求解最短路径问题。在算法实现中，使用数组存储网络中各结点之间的距离，使用二叉堆存储 T 集合，并尽量使用向量化计算加快运行速度。 但在最开始实现 Dijkstra 算法时，我的程序需要花 5 秒才能完成计算。经过逐步优化 ...

Coin Mentioned I’ve been reading Grokking Algorithms, which I recommend to anyone new to algorithms. It’s basically the introduction I wish I had a few months ago! The examples in the book are written ...

ABSTRACT: With the increase of Beijing urban rail transport network, the structure of the road network is becoming more complex, and passengers have more travel options. Together with the complex ...
