Routing Problems and Challenges: A Comprehensive Review

Abstract

Routing problems are fundamental in various domains such as transportation, logistics, communication networks, and supply chain management. They involve finding the most optimal paths or routes for entities to navigate from a source to a destination, subject to various constraints and objectives. This paper provides a comprehensive review of routing problems, categorizes them based on different criteria, and discusses the key challenges associated with solving these problems. The challenges include combinatorial complexity, real-time adaptability, uncertainty, scalability, and trade-offs between conflicting objectives. By understanding these challenges, researchers and practitioners can devise innovative algorithms and strategies to address them effectively.
