XPRSaddcbnewnode
int XPRS_CC XPRSaddcbnewnode(XPRSprob prob, void (XPRS_CC *newnode)(XPRSprob cbprob, void* cbdata, int parentnode, int node, int branch), void* data, int priority);
|
prob
|
The current problem.
|
|
newnode
|
The callback function, which takes five arguments:
myprob,
cbdata,
parentnode,
node and
branch. This function is called every time a new node is created through branching.
|
|
cbprob
|
The problem passed to the callback function,
newnode.
|
|
cbdata
|
The user-defined data passed as
data when setting up the callback with
XPRSaddcbnewnode.
|
|
parentnode
|
Unique identifier for the parent of the new node.
|
|
node
|
Unique identifier assigned to the new node.
|
|
branch
|
The sequence number of the new node amongst the child nodes of
parentnode. For regular branches on a MIP entity this will be either
0 or
1.
|
|
data
|
A user-defined data to be passed to the callback function.
|
|
priority
|
An integer that determines the order in which callbacks of this type will be invoked. The callback added with a higher priority will be called before a callback with a lower priority. Set to 0 if not required.
