When Steve Birkinshaw, the British fell running (越野路跑)champion, planned his record- breaking route across the 214 peaks of the Lake District, it took him six months of preparation and all his years of experience to figure out 1 he thought was the perfect path.

Now two physics students from the University of Manchester who had never visited the mountains have produced a 2 (short) route using a computer algorithm.

Mr Birkinshaw, 52, a researcher at Newcastle University who lives in the Lake District, has had an admirable fell running career, including breaking the 72-year-old record set by Joss Naylor 3 climbing the 214 peaks in the Lake District in only six days and 13 hours in 2014. His record was beaten by seven hours in 2019 by Paul Tierney, who followed Birkinshaw’s carefully mapped route over 512km and 36,000m of climbing.

Mr Birkinshaw, who advised the students, thought 4 would be impossible to improve the route with a computer, ” but they 5 (prove) me wrong“, he said.

“The problem is you change one thing in the route and it’s a domino effect and everything else changes. I would have to spend two to three hours a week for six months 6 (redraw) the route on a computer to work out how long a slight adjustment would change the time 7 now they have the algorithms they can put in all the peaks and find out instantly?”

To figure out their route, the pair used satellite imaging data of the area, with 8 complex data functions were coupled to describe how fest people can move along different routes. This allowed them to work out the energy costs of moving between each peak.

They 9 (feed) all that information into an off-the-shelf solver for the travelling salesman problem, a classic computational science problem for finding out the fastest delivery routes along road networks. Their achievement opens up possibilities to update running records and 10 one day help to deliver aid in badly mapped areas of the world.

By 1954, Christiansen’s son, Godtfred, 6 (become) the junior managing director of the Lego Group. It was during his conversation with an overseas buyer 7 he was struck by the idea of a toy system.

For over 30 years, the Lego Company made only toys and related goods. Then, in 1968, the company opened its 8 (one) Legoland in Denmark. Combining the Lego building bricks with a computer, the Robotics Invention System 1.5 is now the most advanced toy in the Lego Company, which is targeted at 9 (use) aged twelve and above, and that includes any parents or grandparents that want to join in.

Now the Lego Company is expanding its production lines to include lights, cameras and so on. Lego Company has done a lot to entertain many children 10 (globe).
