Public Attributes |
int | parentID |
| parentID is the node ID of the parent
|
int | nodeID |
| nodeID is the node ID
|
int | rowIdxNumNonz |
| rowIdxNumNonz is the number of non-zero elements in rowIndex
|
int * | rowIdx |
| rowIdx is a vector of row indexes for which we are setting the upper and lower bounds
|
double * | rowUB |
| rowUB is a vector of row upper bounds
|
double * | rowLB |
| rowLB is a vector of row lower bounds
|
double | lpValue |
| lpValue is the LP relaxation for the node
|
int | thetaNumNonz |
| thetaNumNonz is the number of non-zero elements in the theta variable solution at this node
|
int * | thetaIdx |
| theta is an array of primal solution variable indexes
|
double * | theta |
| theta is an array of primal positive values this is used for branching and creating new children nodes
|
std::vector< std::pair< int,
int > > | colBasisStatus |
| colBasisStatus is vector of integer pairs, for each element of the vector we store the pair (index, status) where status is: basis code:
|
std::vector< std::pair< int,
int > > | rowBasisStatus |
| rowBasisStatus is the vector of pairs for rows
|
std::set< int > | reducedCostIdx |
| reducedCostVec will hold variables within a tolerance on their reduced costs.
