The full form of DLS in cricket is Duckworth-Lewis-Stern method. It is a mathematical formulation designed to calculate the target score for the team batting second in a limited overs cricket match that is interrupted due to weather or other factors. The DLS method is an attempt to set a statistically fair target for the second teams innings, which is the same difficulty as the original target. The basic principle is that each team in a limited-overs match has two resources available with which to score runs (overs to play and wickets remaining), and the target is adjusted proportionally to the change in the combination of these two resources. The DLS method was first used in a match between Zimbabwe and England on January 1, 1997, and was officially adopted by ICCs calculation method for rain-affected games in 1999. The DLS method was renamed the Duckworth-Lewis-Stern method (or DLS method) in November 2014 after Professor Steven Stern became the method’s custodian.
