This section contains examples that illustrate the options and syntax of PROC OPTMILP. Example 12.1 demonstrates a model contained in an MPS-format SAS data set and finds an optimal solution by using PROC OPTMILP. Example 12.2 illustrates the use of standard MPS files in PROC OPTMILP. Example 12.3 demonstrates how to warm start PROC OPTMILP. More detailed examples of mixed integer linear programs, along with example SAS code, are given in Chapter 7.
