A 21-year-old man from Vidin was arrested after a thief reported stealing his phone, which contained the keys to his cryptocurrency wallet. ^[1] Police from the Directorate for Combating Organized Crime (GDPO) investigated the origin of the Bitcoin and discovered the man had been holding his girlfriend captive since 2024. ^[2] The authors identified a failure mode in which aggregation itself induces reward hacking, where static projection aliases qualitatively different reward profiles into a single scalar. ^[3] The authors propose Adaptive Multi-Reward Projection (AMRP), a lightweight online method that reallocates aggregation weights using three signals: relative shortfall, reward volatility, and recent progress. ^[4] The man forced his girlfriend to perform sexual acts for an online webcam platform to generate income, earning between 2,000 and 6,000 euros per month. ^[5] The thief successfully transferred approximately 50,000 euros worth of Bitcoin from the victim's wallet using the stolen phone keys. ^[6] Across structured reasoning, citation-grounded generation, and open-ended alignment under GRPO, AMRP consistently improves reward-profile balance and downstream performance over fixed and dynamic weighting baselines. ^[7] Reinforcement learning fine-tuning of large language models increasingly adopts multiple reward dimensions, including verifiable rules, task-specific evaluators, and learned reward models, to provide richer supervision across diverse capabilities. ^[8]
