XPRSaddsets, XPRSaddsets64

Purpose
Allows sets to be added to the problem after passing it to the Optimizer using the input routines.
Topic areas
Problem Creation, MIP Entities
Synopsis
int XPRS_CC XPRSaddsets(XPRSprob prob, int nsets, int nelems, const char settype[], const int start[], const int colind[], const double refval[]);

int XPRS_CC XPRSaddsets64(XPRSprob prob, int nsets, XPRSint64 nelems, const char settype[], const XPRSint64 start[], const int colind[], const double refval[]);
Arguments
prob 
The current problem.
nsets 
Number of new sets.
nelems 
Number of new nonzeros in the added sets.
settype 
Character array of length nsets containing the set types:
1 
indicates a SOS1;
2 
indicates a SOS2;
start 
Integer array of length nsets containing the offsets in the colind and refval arrays of the start of the elements for each set.
colind 
Integer array of length nelems containing the (contiguous) column indices for the elements in each set.
refval 
Double array of length nelems containing the (contiguous) reference values. These define the order for SOS2 constraints and may be used in branching for both types.
Further information
1. Reference values must be sufficiently distinct (see SOSREFTOL).
2. This function cannot be called while the current problem is being solved or when it is in an interrupted state. Use XPRSpostsolve to restore the problem to a non-solving state.
