odatse-LEED provides a direct problem solver for ODAT-SE that uses SATLEED developed by M. A. Van Hove for the analyses of the low-energy electron diffraction (LEED) data. SATLEED calculates diffraction data for given atomic positions. Regarding this as a direct problem, it corresponds to an inverse problem to find optimal atomic coordinates that reproduce the diffraction data obtained from the experiment. ODAT-SE provides a framework to solve these inverse problems.

In this tutorial, we will instruct how to use odatse-LEED to find optimal configuration by the grid search (mapper). We use odatse-LEED program included in odatse-LEED with input files in TOML format. Next, we will explain how to write your own main program for analyses.

• Optimization by Grid search
• Analyses by user programs
