Deciding Rain-Affected Cricket Matches: The Duckworth-Lewis Method
In limited overs cricket, the need arises of settling rain-affected matches in a way that is fair to both teams, even if the burden of disruption has been uneven. Starting in the late 1990s, various algorithms have been proposed. The one that is used almost universally is the Duckworth–Lewis method. Each team has two kinds of resources that it can convert into scoring: the number of balls yet to face and the number of batsmen in reserve. The Duckworth–Lewis method involves placing a numerical value on all possible combinations of these resources.
