BRANCHDISJ

Branch and Bound: Determines whether the optimizer should attempt to branch on general split disjunctions during the branch and bound search.

Integer

-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.

Note Split disjunctions are a special form of disjunctions that can be written as

∑_j m_j x_j ≤ m₀ ∨ ∑_j m_j x_j ≥ m₀+1

The split disjunctions created by the optimizer will use a combination of binary or integer variables x_j, with integer coefficients m_j.

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.
