DET_COMPRESS determinant compression utility

DET_COMPRESS compresses multi-determinant expansions for rapid evaluation in quantum Monte Carlo calculations.

Features:

• Fast, memory-efficient compression of large multi-determinant expansions
• Written in portable, standards-compliant Fortran 95 and C89
• Uses CASL file format for data exchange
• Compressed expansions automatically tested for correctness
• Includes source of required libraries for ease of installation
• Licensed under the GPLv3 (see README for details)

Contents of the distribution:

• DET_COMPRESS source code
• LP_SOLVE source code
• Documentation in the form of README files
• Sample programs illustrating how to interface with DET_COMPRESS and use the resulting compressed expansions
• Sample multi-determinant expansions in uncompressed and compressed form

Authors: Gihan L Weerasinghe, Pablo López Ríos (maintainer), and Richard J Needs.
