Revisiting the Complexity of Finding Globally Minimum Energy Configurations in Atomic Clusters
G. W. Greenwood
Abstract
It has previously been proven that finding the globally minimum energy configuration of an atomic cluster belongs in the class of NP-hard problems. However, this proof is limited only to homonuclear clusters. This paper presents a new proof which shows finding minimum energy configurations for heteronuclear clusters is also NP-hard.
