I'm researching the travelling salesman problem and looking for data regarding the current state of affairs regarding solutions and performance. So far the only data I've states that the current record for optimality is held by 'Concorde' which found a solution for a graph containing 85,900 cities. I've also found benchmarking data for Concorde, as well as data pertaining to the current best performance for a world map.
Is this data still accurate? It looks like a lot of this hasn't been updated since the early 2000s.
