Solver Options

Murxla supports option fuzzing, that is, randomly configuring solver options based on the options model of the solver. This options model is advertised to Murxla via configuring a murxla::SolverOption for each option and adding it to the solver manager via murxla::Solver::configure_options() (for more details, see how to configure solver options).

Murxla supports Boolean options (murxla::SolverOptionBool), numeric options (murxla::SolverOptionNum) and options with multiple string values (murxla::SolverOptionList).

class murxla::SolverOption

Base class representing a solver option.
