  reduction
       
          (Or "contraction") The process of transforming an expression
          according to certain reduction rules.  The most important
          forms are beta reduction (application of a lambda
          abstraction to one or more argument expressions) and delta
          reduction (application of a mathematical function to the
          required number of arguments).
       
          An evaluation strategy (or reduction strategy), determines
          which part of an expression (which redex) to reduce first.
          There are many such strategies.
       
          See graph reduction, string reduction, normal order
          reduction, applicative order reduction, parallel
          reduction, alpha conversion, beta conversion, delta
          conversion, eta conversion.
