DESCRIPTION: <strong>Computer scientist Daniël van den Berg demonstra
 tes that difficult problems can appear in unexpected places.</strong>
  Not all computer problems are equally difficult. In his research, Va
 n den Berg and his fellow researchers searched for the very hardest p
 roblems within a class. They found these problems in an unexpected pl
 ace: among the very easiest problems. The research was conducted usin
 g computer simulations and runtime. Van den Berg and his colleagues h
 ope to eventually demonstrate what these most difficult problems look
  like and how they can be made easier. For example, could the Dutch R
 ailways (NS) timetable be simplified by adding or removing a few kilo
 meters of track? More information on the <a href="https://hdl.handle.
