Detailed Description

An implementation of SolverInterface for the commercially-licensed MOSEK (TM) solver (https://www.mosek.com/).

Drake downloads and builds MOSEK automatically, but to enable it you must set the location of your license file as described in the documentation at https://drake.mit.edu/bazel.html#mosek.

The MOSEKLM_LICENSE_FILE environment variable controls whether or not SolverInterface::enabled() returns true. Iff it is set to any non-empty value, then the solver is enabled; otherwise, the solver is not enabled.

Note
MOSEK only cares about the initial guess of integer variables. The initial guess of continuous variables are not passed to MOSEK. If all the integer variables are set to some integer values, then MOSEK will be forced to compute the remaining continuous variable values as the initial guess. (MOSEK might change the values of the integer/binary variables in the subsequent iterations.) If the specified integer solution is infeasible or incomplete, MOSEK will simply ignore it. For more details, check https://docs.mosek.com/10.1/capi/tutorial-mio-shared.html?highlight=initial

MOSEK supports many solver parameters. You can refer to the full list of parameters in https://docs.mosek.com/10.1/capi/param-groups.html#doc-param-groups. On top of these parameters, we also provide the following additional parameters

Member Function Documentation

◆ AcquireLicense()

static std::shared_ptr<License> AcquireLicense ( )
static

This acquires a MOSEK license environment shared among all MosekSolver instances; the environment will stay valid as long as at least one shared_ptr returned by this function is alive.

Call this ONLY if you must use different MathematicalProgram instances at different instances in time, and repeatedly acquiring the license is costly (e.g., requires contacting a license server).

Returns
A shared pointer to a license environment that will stay valid as long as any shared_ptr returned by this function is alive. If MOSEK is not available in your build, this will return a null (empty) shared_ptr.
Exceptions
std::exceptionif MOSEK is available but a license cannot be obtained.
