| Abstract: | As non-strict functions exist in FFP language, we evaluate non-strict functions under eager evaluation. It not only cuts down the execution efficiency but also leads to the computation failure. This paper presents some reduction rules of implementation of the lazy evaluation for some non-strict functions in FCC and compares the execution efficiency of a non-strict function under eager evaluation and under lazy evalualion on Micro-VAX 3500 machine. |
