Returns true iff the program's attributes are compatible with this solver's capabilities.

Returns true iff support for this solver has been compiled into Drake.
When this method returns false, the Solve method will throw.
Most solver implementations will always return true, but certain solvers may have been excluded at compile-time due to licensing restrictions, or to narrow Drake's dependency footprint. In Drake's default build, only commercially-licensed solvers might return false.
Contrast this with enabled(), which reflects whether a solver has been configured for use at runtime (not compile-time).
For details on linking commercial solvers, refer to the solvers' class overview documentation, e.g., SnoptSolver, MosekSolver, GurobiSolver.

Returns true iff this solver is properly configured for use at runtime.
When this method returns false, the Solve method will throw.
Most solver implementation will always return true, but certain solvers require additional configuration before they may be used, e.g., setting an environment variable to specify a license file or license server. In Drake's default build, only commercially-licensed solvers might return false.
Contrast this with available(), which reflects whether a solver has been incorporated into Drake at compile-time (and has nothing to do with the runtime configuration). A solver where available() returns false may still return true for enabled() if it is properly configured.
The mechanism to configure a particular solver implementation is specific to the solver in question, but typically uses an environment variable. For details on configuring commercial solvers, refer to the solvers' class overview documentation, e.g., SnoptSolver, MosekSolver, GurobiSolver.

Describes the reasons (if any) why the program is incompatible with this solver's capabilities.
If AreProgramAttributesSatisfied would return true for the program, then this function returns the empty string.

Solves an optimization program with optional initial guess and solver options.
Note that these initial guess and solver options are not written to prog. If the prog has set an option for a solver, and solver_options contains a different value for the same option on the same solver, then solver_options takes priority. Derived implementations of this interface may elect to throw std::exception for badly formed programs.
