FLT denotes a file format for specifying filters (either diversity filters or range filters) associated with the solution pool of an application of ILOG CPLEX. This section documents that format.
For more general information about the solution pool, see Solution Pool: Generating and Keeping Multiple Solutions of the ILOG CPLEX User's Manual. For an introduction to these filters and their purpose, along with examples of their use, see also Diversity Filters and Range Filters of the ILOG CPLEX User's Manual.
