.SH DESCRIPTION
.B 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.

Further information on SDP and SDPA can be found at

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
.TP
.B \-dimacs

.TP
.B \-numThreads
number of pthreads for internal computation
