Description
This parameter sets the number of nodes explored when CPLEX is solving a subMIP.
With this parameter, you can change the limit on the number of nodes
explored when CPLEX solves a subMIP of a MIP.
See the documentation of these other subMIP parameters
for further instructions that you can impose when CPLEX solves a subMIP:
Tip: This rarely used parameter is helpful only in rare "corner" cases
where there is clear evidence that the default limit
is really inappropriate for this particular problem.
For a definition of subMIP and for a list of conditions in which CPLEX solves a subMIP, see the topic What is a subMIP? in the CPLEX User's Manual.
Values
Any positive integer; default: 500.
