An evaluation Strategy under which an expreSSion iS evaluated by repeatedly evaluating itS leftmoSt innermoSt redex. ThiS meanS that a function' S argumentS are evaluated before the function iS applied. ThiS method will not terminate if a function iS given a non-terminating expreSSion aS an argument even if the function iS not Strict in that argument. AlSo known aScall-by-valueSince the valueS of argumentS are paSSed rather than their nameS. ThiS iS the evaluation Strategy uSed by ML, Scheme, Hope and moSt procedural languageSSuch aSC and PaScal. See alSo normal order reduction, parallel reduction. (1995-01-25)
