Solving a 400-piece jigsaw puzzle should be a doddle – but it’s won a
computer a new world record.
The previous record of 320 pieces was established by a Danish team in 2008 –
but their computer could only solve puzzles with simple cartoon-style pictures
featuring clear shapes and a limited number of colours.
The new software, developed by Taeg Sang Cho and colleagues at the
Massachusetts Institute of Technology, can cope with any image, including
photographs of outdoor scenes.
