The Marginal Value Theorem (MVT) is a principle in optimal foraging theory, which is a branch of ecology that studies how animals search for and exploit food resources. The theorem was developed by ecologist Eric Charnov in 1976. It addresses the decision-making process of foragers—animals that seek food—regarding when to leave a food patch or resource base and move on to a new one.
