dsdp5 - semidefinite program solver SYNOPSIS
dsdp5 [options] filename maxcut [options] filename theta filename DESCRIPTION
This manual page documents briefly the dsdp5, theta and maxcut commands. dsdp5 -- interface to solve general semi-definite programs maxcut -- solves a SDP relaxation of the maximum cut problem theta -- solves the Lovasz thetha problem OPTIONS
A summary of options is included below. For a complete description, see /usr/share/doc/dsdp-doc. -help Show summary of options. -v, --version Show version of program. -print print information at each k iteration (default 10) -save filename of solution file in SDPA format -fout filename to print standard monitor to a file -y0 filename for initial solution file -benchmark filename to file containing names of SDPA files -directory path to directory containing benchmark SDPA files -suffix suffix to add to each benchmark problem name -dloginfo print more information for higher numbers (default 0) -dlogsummary print timing information (default 1 - enabled) -gaptol gap tolerance parameter, stop when relative duality gap less than this gap (default 1e-6) -r0 if nonnegative, initialize S by adding this multiple of the identity matrix (default -1) -penalty penalize dual infeasibility (default 1e10) -boundy bound for variables y (default 1e7) -maxit set maximum iterates (default 200) -zbar Upper bound for dual solution (default 1e10) -mu0 if positive, set initial barrier parameter (default -1) -rho Potential parameter as multiple of dimension (default 3) -drho Use dynamic rho strategy (default 1) -pnormtol stop only if pnorm less than (default 1e30) -reuse Reuse the Schur Matrix this many times (default 4) -dobjmin apply a known lower bound for the objective at solution as a constraint. -bigM if positive, modify algorithm to make dual infeasibility positive with a large associated cost (default 0) -dloginfo print more information for higher numbers (default 0) -params filename to read selected options from a file SEE ALSO

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

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
