Dhaka -The Bangladesh Cricket Board (BCB) on Thursday expressed condolence at the death of a mathematician and statistician Tony Lewis.
Lewis was 78.
Lewis is the co-creator of the Duckworth-Lewis-Stern (DLS) method for deciding weather-affected limited-overs matches in the game of cricket.
BCB CEO Nizam Uddin Chowdhury said Tony Lewis revolutionised the cricket with a method that is considered the fairest in settling weather-interrupted games.
His contribution will be forever remembered, he added.
Lewis and fellow statistician Frank Duckworth had co-devised the system originally called the Duckworth-Lewis method which was first used in 1997 and officially endorsed by the International Cricket Council (ICC) in 1999.
The system calculates targets based on the batting team’s wickets in hand, and overs in hand via mathematical formulas.
In 2014, Prof Steven Stern of Australia’s Bond University became the custodian of the system following the retirements of Duckworth and Lewis.UNB
