The Fast Linear Algorithm
for SU(2) lattice gauge theories

The Fast Linear Algorithm (FLA) uses the rejection method with a function consisting of n steps (see the figure and article for more details)

Download the Fast Linear Algorithm:
1.  To use the Fast Linear Algorithm you must have :
2.  AND you must have the tables in the file "SU2.res". Two choices: . You can choose to download the file SU2.res already done or make one with create_SU2.out (.exe for windows), run it, and follow the instructions.
  • SU2.res   (380 Ko)
    h → [0,100[ with rate=90%
  • For LINUX, only one executable
    create_SU2.out   (For LINUX, 450 Ko)
  • For WINDOWS copy these two programs in the same directory
    1. create_SU2.exe   (For WINDOWS, 34 Ko)
    2. cygwin1.dll   (For WINDOWS, 950 Ko)

    The Fast Linear Algorithm (FLA) is the fastest of all algorithms proposed. We can show more generally that another algorithm cannot be faster (see article).
