This paper reports on a new modular package for the analysis of low energy
electron diffraction (LEED) data. The package, DL_LEED, has been developed
at the CLRC Daresbury Laboratory. The code implements a number of new desig
n features not found in other LEED programs. The code is designed to perfor
m structural optimizations in a variety of modes ranging from full dynamic
searches through to tenser LEED searches and is inherently suitable for par
allel computing architectures. (C) 2001 Elsevier Science B.V. All rights re
