摘要: It has been claimed that logic programs are equivalent to or consequences of specifications. We argue this is generally not correct. Programs often make implicit assumptions about types, leading the possibility incorrect answers. If made explicit, so program specification, less efficient. define when with type declarations correct and show all well typed answers returned by such
