problem.addSlpIntSolCallback

Purpose
Add a user callback to be called during MISLP when an integer solution is obtained
Topic areas
Callback, MISLP
Synopsis
problem.addSlpIntSolCallback(slpintsol, data=None, priority=0)
slpintsol(cbprob, cbdata)
Arguments
slpintsol 
The function to be called when an integer solution is obtained. slpintsol returns an integer value. At present, the return value is ignored.
data 
Address of a user-defined object, which can be used for any purpose by the function. data is passed to slpintsol as cbdata.
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.
cbprob 
The problem passed to the callback function.
cbdata 
The user-defined object passed as data to problem.addSlpIntSolCallback.
Further information
1. This callback must be used during MISLP instead of the problem.addIntsolCallback callback which is used for MIP problems.
2. Note that for SLP-MIP-SLP (see SLPMIPALGORITHM), the slpintsol callback will only be fired once after the second SLP solve terminated, in which case the solution can also only be queried via problem.getSolution but not via problem.getLpSol (unless postsolve is disabled).
