MACS: Multi-Agent Reinforcement Learning for Optimization of Crystal Structures

NeurIPS 2025poster

Geometry optimization of atomic structures is a common and crucial task in computational chemistry and materials design. Following the learning to optimize paradigm, we propose a new multi-agent reinforcement learning method called Multi-Agent Crystal Structure optimization (MACS) to address the pro…

The Complexity of Temporal Vertex Cover in Small-Degree Graphs

AAAI 2022technical

Temporal graphs naturally model graphs whose underlying topology changes over time. Recently, the problems Temporal Vertex Cover (or TVC) and Sliding-Window Temporal Vertex Cover (or Delta-TVC for time-windows of a fixed-length Delta) have been established as natural extensions of the classic Vertex…
