Member Data Documentation

◆ SPLIT_STRATEGY_AUTO

com.google.ortools.sat.SatParameters.SharedTreeSplitStrategy.SPLIT_STRATEGY_AUTO =(0) 
Uses the default strategy, currently equivalent to
SPLIT_STRATEGY_DISCREPANCY.

SPLIT_STRATEGY_AUTO = 0;

Definition at line 1728 of file SatParameters.java.

◆ SPLIT_STRATEGY_AUTO_VALUE

final int com.google.ortools.sat.SatParameters.SharedTreeSplitStrategy.SPLIT_STRATEGY_AUTO_VALUE = 0
static 
Uses the default strategy, currently equivalent to
SPLIT_STRATEGY_DISCREPANCY.

SPLIT_STRATEGY_AUTO = 0;

Definition at line 1786 of file SatParameters.java.

◆ SPLIT_STRATEGY_BALANCED_TREE

com.google.ortools.sat.SatParameters.SharedTreeSplitStrategy.SPLIT_STRATEGY_BALANCED_TREE =(3) 
Attempt to keep the shared tree balanced.

SPLIT_STRATEGY_BALANCED_TREE = 3;

Definition at line 1758 of file SatParameters.java.

◆ SPLIT_STRATEGY_BALANCED_TREE_VALUE

final int com.google.ortools.sat.SatParameters.SharedTreeSplitStrategy.SPLIT_STRATEGY_BALANCED_TREE_VALUE = 3
static 
Attempt to keep the shared tree balanced.

SPLIT_STRATEGY_BALANCED_TREE = 3;

Definition at line 1816 of file SatParameters.java.

◆ SPLIT_STRATEGY_DISCREPANCY

com.google.ortools.sat.SatParameters.SharedTreeSplitStrategy.SPLIT_STRATEGY_DISCREPANCY =(1) 
Only accept splits if the node to be split's depth+discrepancy is minimal
for the desired number of leaves.
The preferred child for discrepancy calculation is the one with the
lowest objective lower bound or the original branch direction if the
bounds are equal. This rule allows twice as many workers to work in the
preferred subtree as non-preferred.

SPLIT_STRATEGY_DISCREPANCY = 1;

Definition at line 1741 of file SatParameters.java.

◆ SPLIT_STRATEGY_DISCREPANCY_VALUE

final int com.google.ortools.sat.SatParameters.SharedTreeSplitStrategy.SPLIT_STRATEGY_DISCREPANCY_VALUE = 1
static

◆ SPLIT_STRATEGY_FIRST_PROPOSAL

com.google.ortools.sat.SatParameters.SharedTreeSplitStrategy.SPLIT_STRATEGY_FIRST_PROPOSAL =(4) 
Workers race to split their subtree, the winner's proposal is accepted.

◆ SPLIT_STRATEGY_OBJECTIVE_LB

com.google.ortools.sat.SatParameters.SharedTreeSplitStrategy.SPLIT_STRATEGY_OBJECTIVE_LB =(2)

no objective, this is equivalent to SPLIT_STRATEGY_FIRST_PROPOSAL.

SPLIT_STRATEGY_OBJECTIVE_LB = 2;
