Understanding File Formats on page 144 in this manual lists the file formatsbriefly, and the ILOG CPLEX Reference Manual documents file formats, such as MPS, LP,and others.◆◆To read MIP problem data into the Interactive Optimizer, use the read command with anoption to indicate the file type.To read MIP problem data into your application, use the importModel method inConcert Technology or use CPXreadcopyprob in the Callable Library.Displaying MIP ProblemsTable 14.2 summarizes display options in the Interactive Optimizer that are specific to MIPproblems.Table 14.2 Interactive Optimizer Display Options for MIP ProblemsInteractive commanddisplay problem binariesdisplay problem generalsdisplay problem semi-continuousdisplay problem integersdisplay problem sosdisplay problem statsPurposelists variables restricted to binary valueslists variables restricted to integer valueslists variables of type semi-continuous andsemi-integerlists all of the abovelists the names of variables in one or moreSpecial Ordered Setslists LP statistics plus:• binary variable types, if present;• general variable types, if present;• and number of SOS, if present.In Concert Technology, use one of the accessors supplied with the appropriate object class,such as IloSOS2::getVariables.From the Callable Library, use the routines CPXgetctype and CPXgetsos to access thisinformation.258 ILOG CPLEX 11.0 — USER’ S MANUAL
