摘要

摘要

En 中文
In many molecular dynamics simulation software packages and hardware implementations, piecewise polynomials are used to represent and compute pairwise potential functions efficiently. In this paper, we present three modifications applicable to most interpolations to increase their accuracy. The increased accuracy reduces the amount of data that needs to be stored for each interaction potential, making such interpolations more suitable for architectures with limited memory and/or cache or hardware implementations.
