A guided-ejection memetic algorithm for the three-objective VRPTW: Fleet, distance and workload balance

The vehicle routing problem with time windows (VRPTW) underpins distribution and field-service operations, yet most multi-objective treatments optimise only fleet size and travelled distance, and rely on generic evolutionary operators that struggle to move the discrete, rugged fleet-size axis. We study a three-objectiv...

An improved Inception Transformer with Bi-Level Routing Attention and multi-scale feature collaborative enhancement for Chinese ancient architecture image classification

Chinese ancient architecture embodies China’s cultural heritage but remains challenging to classify because of spatially dispersed key components, high inter-class similarity, and multi-scale visual characteristics. To address these challenges, we propose BDM-ViT, an improved Vision Transformer model based on the Inc...

Causal Benefit-Aware Recommendation for Personalized Learning-Path Features: A Targeting-Policy Framework with Provable Guarantees and Randomized Evaluation

This work formalizes feature recommendation as a causal targeting-policy problem: rank students by the estimated conditional average treatment effect (CATE) of a feature and recommend to the top of the ranking, proving causal top-CATE targeting maximizes policy value at any budget and weakly dominates predictive (outco...
