Reading SDPA files

DSDP can also be run without the MATLAB environment if the user has a problem written in sparse SDPA format. These executables have been put in the directory DSDPROOT/exec/. The file name should follow the executable. For example,

> dsdp5 truss4.dat-s

Other options can also be used with DSDP. These should follow the SDPA filename.

l

[-gaptol <rtol>] to stop the problem when the relative duality gap is less than this number.

l

[-mu0 <mu0>] to specify the initial barrier parameter.

l

[-r0 <r0>] to specify the initial value of $r$ in (DD).

l

[boundy <1e6>] to bound the magnitude of each variable $y$ in (DD).

l

[-save <filename>] to save the solution into a file with a format similar to SDPA.

l

[-y0 <filename>] to specify an initial vector $y$ in (D).

l

[-maxit <iter>] to stop the problem after a specified number of iterations.

l

[-rho <3>] to set the potential parameter $\rho$ to this multiple of the conic dimension.

l

[-dobjmin <dd>] to add a constraint that sets a lower bound on the objective value at the solution.

l

[-penalty <1e8>] to set the penalty parameter for infeasibility in (D).

l

[-print <1>] print standard output at each $k$ iteration.

l

[-bigM <0>] treat the inequality $r \geq 0$ in (DD) as other inequalities and keep it positive.

l

[-dloginfo <0>] to print more detailed output. Higher number produce more output.

l

[-dlogsummary <1>] to print detailed timing information about each dominant computations.
