A Graph-based Decomposition Framework for Flow-based Charging Station Location Problems

This paper proposes a graph-based decomposition framework that enhances the computational efficiency and scalability of solving flow-based charging station location problems on large-scale transportation networks by partitioning the network into smaller subproblems, solving them individually, and refining the aggregated results.

Inferring personality from a live interaction with an LLM: Predictions are internally consistent and show convergent validity

This preregistered study demonstrates that large language models can reliably infer Big Five personality traits from live conversations with high internal consistency and convergent validity, particularly for neuroticism and agreeableness, though performance varies by trait observability and prompting strategy.
