XPRSaddcbchgnode |
Purpose
This function is deprecated and may be removed in future releases. Declares a callback that is fired every time the code performs a global backtrack to select a node to start a dive on. This callback function will be called in addition to any callbacks already added by XPRSaddcbchgnode.
Synopsis
int XPRS_CC XPRSaddcbchgnode(XPRSprob prob, void (XPRS_CC *f_chgnode)(XPRSprob my_prob, void *my_object, int *nodnum), void *object, int priority);
Arguments
|
prob
|
The current problem.
|
|
f_chgnode
|
The callback function which takes three arguments,
my_prob,
my_object and
nodnum, and has no return value. This function is called every time a new node is selected.
|
|
my_prob
|
The problem passed to the callback function,
f_chgnode.
|
|
my_object
|
The user-defined object passed as
object when setting up the callback with
XPRSaddcbchgnode.
|
|
nodnum
|
A pointer to the number of the node,
