The INTPOINT procedure solves the Network Program with Side Constraints (NPSC) problem using the interior point algorithm.

The data required by PROC INTPOINT are similar to the data required by PROC NETFLOW when solving network flow models using the interior point algorithm.

The constraint data can be specified in either the sparse or dense input format. This is the same format that is used by PROC LP and PROC NETFLOW; therefore, any model-building techniques that apply to models for PROC LP or PROC NETFLOW also apply to PROC INTPOINT.

For more details on PROC INTPOINT refer to Chapter 4, The INTPOINT Procedure.
