Installation

Required libraries and python modules

• python >= 3.9
• pypolymlp
• symfc
• spglib
• joblib

[Optional]

• matplotlib (if plotting RSS results)
• seaborn (if plotting RSS results)

How to install

conda create -n rsspolymlp python=3.11
conda activate rsspolymlp
conda install -c conda-forge pypolymlp symfc spglib joblib
pip install rsspolymlp

Usage

The command-line interface of rsspolylmp is organized into three sections, each corresponding to a different phase of the workflow:

1. Generating initial structures (rss-init-struct)
2. Performing parallel geometry optimization (rss-parallel)
3. Analyzing RSS results (rss-analysis)

Example Commands

rss-init-struct --elements Al Cu --atom_counts 4 4 --num_init_str 2000
rss-parallel --pot polymlp.yaml --num_opt_str 1000
rss-analysis

Arguments

• --elements: List of element symbols (e.g., Al Cu).
• --atom_counts: Number of atoms for each element (must match the order of --elements).
• --num_init_str: Number of random initial structures to generate. (default: 5000)
• --pot: Path to the polynomial MLP potential file. (default: polymlp.yaml)
• --num_opt_str: Maximum number of optimized structures to obtain from RSS. (default: 1000)
