Description: | Report exact basis condition number (if available) in the solver summary. |
Condition numbers are described in Numerical Stability.
This parameter enables the calculation of exact basis condition numbers which are included in the Solver Summary. This parameter has no effect if solver summaries are disabled.
The time required to calculated exact condition numbers varies greatly as a function of the problem size. Exact condition numbers are very fast to calculate for small problems, however the time required grows quickly as the problem size increases. This means that exact summary conditioning can be slow to calculate for very large problems.
Estimated condition numbers (included by default in Solver Summary) are typically very fast to query, even for large problems.
As for estimated basis condition numbers, exact condition numbers require a basic feasible solution. Some problems or Performance settings will not generate a basic feasible solution. One example is Barrier algorithm with Crossover disabled.
