Automatic memory management is defined as any garbage collection technique that automatically gets rid of stale references, making a free operator unnecessary. This is quite an old idea—implementations have been with us for almost as long as the history of modern computer science, probably starting out as reference counting methods in early Lisp machines. After that, other heap management strategies were developed. Most are refinements of tracing techniques, which involve traversing live object graphs on the heap in order to determine what can be garbage collected.
