作者:

Highlights:

• A tailored two-stage routing framework is designed for proximity graph algorithms.

• Optimized guided search significantly accelerates routing in the first stage to better meet the efficiency requirement.

• Optimized greedy algorithm comprehensively detects the results in the second stage to better meet the accuracy requirement.

• Theoretical and experimental analysis demonstrates the state-of-the-art power of the proposed strategy.

• The scalability of the proposed strategy is robust and can be embedded to various proximity graphs.
