7.4 Setting solver parameters¶
MOSEK comes with a large number of parameters that allows the user to tune the behavior of the optimizer. The typical settings which can be changed with solver parameters include:
choice of the optimizer for linear problems,
choice of primal/dual solver,
turning presolve on/off,
turning heuristics in the mixed-integer optimizer on/off,
level of multi-threading,
solver termination criteria,
behaviour of the license manager,
and more. All parameters have default settings which will be suitable for most typical users.
The API reference contains:
Each parameter is identified by a unique name and it can accept either integers, floating point values, symbolic strings or symbolic values. Parameters are set in the structure
param and passed as a separate argument to
Some parameters can accept symbolic strings or symbolic values from a fixed set. The set of accepted values for every parameter is provided in the API reference.
For example, the following piece of code sets up parameters which choose and tune the interior point optimizer before solving a problem.
