Initializing help system before first use

SBBEST

Description
Number of infeasible global entities to initialize pseudo costs for on each node.
Type
Integer
Values
-1 
determined automatically.
0 
disable strong branching.
n>0 
perform strong branching on up to n entities at each node.
Default value
-1
Note

By default, strong branching will be performed only for infeasible global entities whose pseudo costs have not otherwise been initialized (see HISTORYCOSTS).

If SBBEST is set to zero, the control HISTORYCOSTS will also be treated as zero and no past branching or strong branching information will be used in the global entity selection.

Affects routines
XPRSmipoptimize ( MIPOPTIMIZE).
