problem.loadCuts

Purpose
Loads cuts from the cut pool into the matrix. Without calling problem.loadCuts the cuts will remain in the cut pool but will not be active at the node. Cuts loaded at a node remain active at all descendant nodes unless they are deleted using problem.delCuts.

Synopsis
problem.loadCuts(cutind, cuttype=0, interp=-1)
Arguments
cutind 
Array containing pointers to the cuts to be loaded into the matrix. These are pointers returned by either problem.storeCuts or problem.getCPCutList.
cuttype 
Cut type.
interp 
The way in which the cut type is interpreted:
-1 
load all cuts;
1 
treat cut types as numbers;
2 
treat cut types as bit-vectors (compare the Optimizer Reference Manual) - load cut if any bit matches any bit set in cuttype;
3 
treat cut types as bit-vectors (compare the Optimizer Reference Manual) - 0 load cut if all bits match those set in cuttype.
Further information
1. This function should be called only from within callback functions set by either problem.addOptnodeCallback, problem.addPrenodeCallback, problem.addNodeLPSolvedCallback or problem.addPreIntsolCallback.
2. Argument cutind may contain xpress.poolcut objects instead of indices.
