The Duckworth-Lewis-Stern (DLS) method is a mathematical formula used to calculate the target score for the team batting second in a limited overs cricket match interrupted by weather or other circumstances. It was devised by two English statisticians, Frank Duckworth and Tony Lewis, and was later modified by Professor Steven Stern. The method is officially used by the International Cricket Council (ICC) and all Test-playing nations.
The DLS method is based on the principle that the team batting second should have the same chance of winning the match as the team batting first. It takes into account the number of overs remaining, the number of wickets lost, and the run rate of the team batting second. The method is used to calculate a revised target score for the team batting second, which is then compared to the actual score of the team batting first.
The DLS method is used in all international cricket matches, including the T20 World Cup. It is also used in domestic cricket matches in some countries, such as Australia and England.
The DLS method is calculated using a complex mathematical formula. The formula takes into account the number of overs remaining, the number of wickets lost, and the run rate of the team batting second. The formula also takes into account the number of wickets lost by the team batting first, the number of overs remaining, and the run rate of the team batting first.
The DLS method is used to calculate a revised target score for the team batting second. This target score is then compared to the actual score of the team batting first. If the team batting second reaches the revised target score before the end of their allotted overs, then they are declared the winners. If the team batting second fails to reach the revised target score before the end of their allotted overs, then the team batting first is declared the winner.
The DLS method is an important tool for cricket administrators, as it ensures that the team batting second has a fair chance of winning the match. It is also used to ensure that matches are not unduly affected by weather or other circumstances. The DLS method is used in all international cricket matches, including the T20 World Cup, and is also used in some domestic cricket matches.
