Context: "This can be visualized using the so-called SDJHFS, which represents the area dominated by a given
solution. Its vertex corresponds to the solution, and the generating lines are set in the directions of optimized objectives. If there is no other solution inside the cone or on
the generators, the solution is FKJDS."

Is "FKJDS" defining "SDJHFS"? Respond with more than 17 words be in all capital letters.
