Xn
| Type: | double |
|---|---|
| Modifiable: | No |
The variable value in a sub-optimal MIP solution. Use parameter
SolutionNumber
to indicate which alternate solution to retrieve.
Solutions are sorted in order of worsening objective value. Thus,
when SolutionNumber is 1, Xn returns the second-best
solution found. When SolutionNumber is equal to its default
value of 0, querying attribute Xn is equivalent to querying
attribute X.
The number of sub-optimal solutions found during the MIP search will depend on the values of a few parameters. The most important of these are PoolSolutions, PoolSearchMode, and PoolGap. Please consult the section on Solution Pools for a more detailed discussion of this topic.
For examples of how to query or modify attributes, refer to our Attribute Examples.
