C++ Reference: class PseudoCosts
Note: This documentation is automatically generated.
Pseudo cost of a variable is measured as average observed change in the
objective bounds per unit change in the variable bounds.
| Method |
GetBestDecisionVar | Return type: IntegerVariable Returns the variable with best reliable pseudo cost that is not fixed.
|
GetCost | Return type: double Arguments: IntegerVariable var Returns the pseudo cost of given variable. Currently used for testing only.
|
GetRecordings | Return type: int Arguments: IntegerVariable var Returns the number of recordings of given variable. Currently used for
testing only.
|
PseudoCosts | Return type: explicit Arguments: Model* model |
UpdateCost | Return type: void Arguments: const std::vector<VariableBoundChange>& bound_changes,
IntegerValue obj_bound_improvement Updates the pseudo costs for the given decision.
