C++ Reference: class ScipConstraintHandlerContext
Note: This documentation is automatically generated.
| Method |
CurrentNodeId | Return type: int64_t |
is_pseudo_solution | Return type: bool Pseudo solutions may not be LP feasible. Duals/reduced costs are not
available (the LP solver failed at this node).
Do not add "user cuts" here (that strengthen LP solution but don't change
feasible region), add only "lazy constraints" (cut off integer solutions).
TODO(user): maybe this can be abstracted away.
|
NumNodesProcessed | Return type: int64_t |
scip | Return type: SCIP* |
ScipConstraintHandlerContext | Arguments: SCIP* scip, SCIP_SOL* solution,
bool is_pseudo_solution A value of nullptr for solution means to use the current LP solution.
|
VariableValue | Return type: double Arguments: const MPVariable* variable |

[null,null,["Last updated 2024-08-06 UTC."],[],["The `ScipConstraintHandlerContext` class provides methods for interacting with the SCIP solver. Key actions include retrieving the `CurrentNodeId` and `NumNodesProcessed`, accessing the underlying `SCIP*` solver instance. `VariableValue` gets the value of a variable. `is_pseudo_solution` checks if the solution is a pseudo solution where duals/reduced costs are not available, and suggests only adding lazy constraints. The class can be created with an instance of `SCIP`, a solution and a boolean.\n"],null,[]]
