Tony Lewis, one of the inventors of the Darkworth -Lewis-Stern or DLS method, has died in a weather-affected limited-overs cricket match. The England and Wales Cricket Board (ECB) made the announcement on Wednesday. The ECB said in a statement that it was " saddened" to learn that Tony Lewis had died at the age of eight . Tony , along with his fellow mathematician Frank Duckworth, invented the Duckworth-Lewis method in 1999. Later in 2014, the mathematical formula named Duckworth-Lewis-Stern is being used all over the world in rain-limited limited overs matches. The Duckworth-Lewis or DLS method is used in limited overs cricket to resolve match results or set new goals due to bad weather. Lewis worked with mathematician Frank Duckworth to determine the outcome of a match due to rain. They first spoke of the 'Duckworth-Lewis method' in 1998. It was later officially adopted by the International Cricket Council (ICC) in 1999. However, after 15 years, its name was changed. In 2014, the new name was given to the Duckworth-Lewis-Stern or DLS method. This method was first implemented in 1998. England bowled out Zimbabwe for 200 runs. Later in this method, the new target stood in front of the English, 18 runs in 42 overs. The English lost the match by 6 runs. Steven Stern, a mathematics professor in Queensland, Australia, has updated the basic methodology considering the scoring-rate of modern cricket. In 2010, Duckworth and Lewis were awarded the fifth highest honors MBE in the British Empire for their contributions to cricket and mathematics.
