file reader for partial primal solutions
- Author
- Jakob Witzig
This reader handles solutions in two formats:
- SCIP raw format
The format is as follows:
line 1: "solution status: <status>"
line 2: "objective value: <value>"
line 3+i: <variable name> <value> (obj: <objective coefficient of variable>)
Only known values need to be listed. - Example:
solution status: optimal
objective value: 1
x1 1 (obj:1)
x2 1 (obj:0)
- XML format
This format is used by CPLEX, for example. For reading we require a section of <variables>. Each entry in this section consists of
<variable name="<name>" index="<number>" value="<value>"/> - Example:
<?xml version = "1.0" standalone="yes"?>
<variables>
<variable name="x1" index="1" value="1"/>
<variable name="x2" index="2" value="1"/>
</variables>
</xml>
