Bingxuan Li, Cheng Qian, Eitan Anzenberg, Heng Ji, Jeonghwan Kim, Niran Kundapur, Xiusi Chen

PEARL uses reinforcement learning and an external memory of inferred preferences to cut errors in resolving calendar conflicts by 55 percent.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments on CalConflictBench show that PEARL achieves an error reduction rate of 0.76 and a 55% improvement in average error rate compared to the strongest baseline.

C2weakest assumption

That the synthetic conflicts and preference signals in CalConflictBench faithfully represent real user decision patterns and that round-wise rewards can be defined without introducing benchmark-specific biases that do not transfer outside the test set.

C3one line summary

PEARL reduces calendar conflict resolution errors by 55% on a new long-horizon benchmark by adding a preference memory and round-wise RL supervision to LLM agents.
