Understanding a molecule that plays a key role in nitrogen fixing – a chemical process that enables life on Earth – has long ...

Cryptography secures communication in banking, messaging, and blockchain. Good algorithms (AES, RSA, ECC, SHA-2/3, ChaCha20) are secure, efficient, and widely trusted. Bad algorithms (DES, MD5, SHA-1, ...

本项目以“带次模惩罚费用的平行机客户订单调度优化”为方向，研究在多台平行机的制造环境下如何有效分配和调度客户订单。次模惩罚费用机制的引入，使得调度模型可以更灵活地反映实际中的分段性惩罚需求——即拒绝订单惩罚不再是固定的，而是随着 ...

A few weeks ago, my ears perked up when a gaggle of middle school volleyball players in my car were talking about the teachers they don’t like; I have an unfortunate appetite for tweenage gossip, and ...

Abstract: Noncommutative constraint satisfaction problems (CSPs) are higher-dimensional operator extensions of classical CSPs. Their approximability remains largely unexplored. A notable example of a ...
