Global Functions
INLINE std::pair<BrkgaParams, ControlParams> BRKGA::readConfiguration( std::istream& input, std::ostream& logger = std::cout )
Reads the parameters from an input stream.
Todo This method can beneficiate from introspection tools. We would like achieve a code similar to the Julia counterpart.
Parameters:
input |
the input stream. It can be a file or a string stream. |
logger |
a output stream to log some information such as missing no-required parameters. It does not log errors. |
std::fstream::failure |
in case of errors in the file. |
Returns:
a tuple containing the BRKGA and external control parameters.
INLINE std::pair<BrkgaParams, ControlParams> BRKGA::readConfiguration( const std::string& filename, std::ostream& logger = std::cout )
Reads the parameters from a configuration file.
Parameters:
filename |
the configuration file. |
logger |
a output stream to log some information such as missing no-required parameters. It does not log errors. |
std::fstream::failure |
in case of errors in the file. |
Returns:
a tuple containing the BRKGA and external control parameters.
INLINE std::ostream& BRKGA::operator << ( std::ostream& os, const BrkgaParams& brkga_params )
Output stream operator for BrkgaParams.
Parameters:
os |
the output stream. |
brkga_params |
the parameters. |
Returns:
the output stream.
INLINE std::ostream& BRKGA::operator << ( std::ostream& os, const ControlParams& control_params )
Output stream operator for ControlParams.
Parameters:
os |
the output stream. |
control_params |
the parameters. |
Returns:
the output stream.
INLINE void BRKGA::writeConfiguration( std::ostream& output, const BrkgaParams& brkga_params, const ControlParams& control_params = ControlParams{} )
Writes the parameters into a output stream.
Note
All floating point parameters are written with two point precision.
Todo This method can beneficiate from introspection tools. We would like achieve a code similar to the Julia counterpart.
Parameters:
output |
the output stream. |
brkga_params |
the BRKGA parameters. |
control_params |
the external control parameters. Default is an empty object. |
std::fstream::failure |
in case of errors in the file. |
INLINE void BRKGA::writeConfiguration( const std::string& filename, const BrkgaParams& brkga_params, const ControlParams& control_params = ControlParams{} )
Writes the parameters into a configuration file.
Note
All floating point parameters are written with two point precision.
Parameters:
filename |
the configuration file. |
brkga_params |
the BRKGA parameters. |
control_params |
the external control parameters. Default is an empty object. |
std::fstream::failure |
in case of errors in the file. |
