NAME

       SDPA - High-performance software package for SemiDefinite Programs

SYNOPSIS

       sdpa   DataFile   OutputFile   [InitialPtFile]  [-pt  parameters]  [-dimacs]  [-numThreads
        numThreads]
       sdpa [options] files...
       sdpa --version

DESCRIPTION

       sdpa - "SDPA (SemiDefinite Programming Algorithm)" is one of the most efficient and stable
       software packages for solving SDPs based on the primal-dual interior-point method.

       SDP  (SemiDefinite  Program)  is used for financial engineering, machine learning, control
       theory, sensor network problem,  quantum  chemistry,  quantum  information,  combinatorial
       optimizaiton, polynomial optimization, and so on.

       Futher information on SDP and SDPA can be found at

OPTIONS

       ---- option type 1 ----
       sdpa   DataFile   OutputFile   [InitialPtFile]  [-pt  parameters]  [-dimacs]  [-numThreads
       numThreads]
       parameters = 0 default, 1 fast (unstable), 2 slow (stable)
       example1-1: sdpa example1.dat example1.result
       example1-2: sdpa example1.dat-s example1.result
       example1-3: sdpa example1.dat example1.result example1.ini
       example1-4: sdpa example1.dat example1.result -pt 2
       example1-5: sdpa example1.dat example1.result -dimacs
       example1-6: sdpa example1.dat example1.result -numThreads 4
       ---- option type 2 ----
       sdpa [option filename]+
         -dd : data dense :: -ds : data sparse
         -id : init dense :: -is : init sparse
         -o  : output     :: -p  : parameter
         -pt : parameters , 0 default, 1 fast (unstable)
                            2 slow (stable)
       example2-1: sdpa -o example1.result -dd example1.dat
       example2-2: sdpa -ds example1.dat-s -o example1.result -p param.sdpa
       example2-3: sdpa -ds example1.dat-s -o example1.result -pt 2
       example2-4: sdpa -ds example1.dat-s -o example1.result -dimacs
       example2-5: sdpa -ds example1.dat-s -o example1.result -numThreads 4
       ---- option type 3 ----
       sdpa --version
       to print out version and exit.

       PARAMETER_FILE
              is decided by the following priority
                 1: The file assigned by '-p' option of 'option type 2'.
                     For 'option type1', this is skipped.
                 2: ./param.sdpa
                     For 'option type2', this is skipped.
                 3: /usr/share/sdpa/param.sdpa
                 4: Default parameter

       -dimacs
              printout dimacs information incurring additional computation cost

       -numThreads
              number of pthreads for internal computation
