Algorithms To Reassemble Ancient Map of Rome

MattJ writes "The BBC reports on a Stanford project to reconstruct pieces of an ancient, detailed, 60' by 43' 'map of Rome carved into stone slabs about AD 210 but later broken into fragments.' ... So complicated is the jumble of parts that for decades the map pieces have been referred to as 'the biggest jigsaw in the world.' Researchers developed algorithms to assemble the 3D fragments of the map, and have had some success."
