void write	(	std::string	file,
		std::string	format = "MPS"
	)		const [inline]

This function writes the problem or the solution to a file in the given format. Trying to write in an unsupported format will trigger LpBase::UnsupportedFormatError.

Parameters:

file	The file path
format	The output file format. Supportted formats are "MPS" and "LP".

Reimplemented from LpBase.
