static

reads a given SCIP solution file, problem has to be transformed in advance

Parameters

scip	SCIP data structure
fname	name of the input file
xml	true, iff the given file is XML

problem reading method of reader

In order to determine the type of the file, we have to open it. Thus, it has to be opened twice. This might be removed, but is likely to not hurt the performance too much.
