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

---- 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

example2-5: 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
