MAXNODE

Description
Branch and Bound: Specifies the maximum number of nodes that will be explored.
Type
Integer
Topic areas
Limits, Branch and Bound Search
Values
≥0 
The maximum number of Branch and Bound nodes that will be explored.
Default value
INF
Unit
nodes
Notes
When MAXNODE is set on an objective using XPRSsetobjintcontrol, then when the limit is reached the solver will stop the current solve but will continue with solving the next objective. This is in contrast to the behaviour when MAXNODE is set on the problem with XPRSsetintcontrol, where the overall optimization will be terminated as soon as the limit is reached.
When MAXNODE is set to 0, the solver will stop after the root node.
Affects routines
XPRSmipoptimize ( MIPOPTIMIZE).
