Detailed Description

file reader for primal solutions

Author

Tobias Achterberg

Marc Pfetsch

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 nonzero 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>
