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 http://sdpa.sourceforge.net/ 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 AUTHOR
