MSE Attributes
| MSE_DIVERSITYSUM |
Sum of diversity metrics for the current set of solutions.
|
| MSE_METRIC_DIVERSITY |
The diversity metric for a solution is the sum of difference metrics between the solution and all others in the current set. The difference value between two solutions is either calculated internally by the MIP solution enumerator (using a simple difference metric that considers only the MIP entities in the solution) or else by the user in a callback defined with a call to XPRS_mse_setcbgetsolutiondiff.
|
| MSE_METRIC_MIPOBJECT |
MIP objective value.
|
| MSE_METRIC_MODOBJECT |
User-defined modified objective. The user can assign a solution with an objective value that reflects the 'true' objective of the solution in cases where the MIP objective does not completely model the user's problem. The user needs to return this value from a callback passed to the enumeration-run routines XPRS_mse_minim, XPRS_mse_maxim and XPRS_mse_opt. This routine will be some customized version of the XPRS_mse_defaulthandler routine provided with the FICO Xpress Optimizer.
|
| MSE_SOLUTIONS |
The number of solutions found and currently stored by the MIP solution enumerator.
