"Slim" Benchmark Sets for Faster Method Development

Area of Science:

• Computational chemistry
• Quantum chemistry method development

Background:

• Large benchmark sets accelerate quantum chemistry method advancement, particularly for density functional theory.
• Existing large sets are often unsuitable for developing novel, inefficient computational methods due to size limitations.

Purpose of the Study:

• Introduce Slim benchmark sets to facilitate the development of cutting-edge quantum chemistry methods.
• Address the challenge of handling large molecules with inefficient research codes.

Main Methods:

• Developed Slim benchmark sets by summarizing statistics from larger counterparts.
• Restricted molecule sizes to 5, 16, and 20 atoms for efficient treatment by new implementations.

Main Results:

• Slim benchmark sets effectively summarize the statistical properties of larger datasets.
• 16 and 20 atom Slim sets accurately represent reactions involving significantly larger numbers of atoms.

Conclusions:

• Slim benchmark sets enable the use of data-driven methodologies in the early stages of developing novel quantum chemistry approaches.
• These smaller, representative sets are crucial for advancing computational chemistry research codes.
