BRANCHDISJ

Description
Branch and Bound: Determines whether the optimizer should attempt to branch on general split disjunctions during the branch and bound search.
Type
Integer
Topic area
Branching
Values
-1 
Automatic selection of the strategy.
0 
Disabled.
1 
Cautious strategy. Disjunctive branches will be created only for general integers with a wide range.
2 
Moderate strategy.
3 
Aggressive strategy. Disjunctive branches will be created for both binaries and integers.
Default value
-1
Notes
Note Split disjunctions are a special form of disjunctions that can be written as
∑j mj xj ≤ m0 ∨ ∑j mj xj ≥ m0+1
The split disjunctions created by the optimizer will use a combination of binary or integer variables xj, with integer coefficients mj.
Split disjunctions for branching will always be created with a default priority value of 400 instead of the default value of 500 for regular entity branches.
