cheney's algorithm, first described in a 1970 acm paper by c.j. cheney, is a stop and copy method of tracing garbage collection in computer software systems. in this scheme, the heap is divided into two equal halves, only one of which is in use at any one time. garbage collection is performed by copying live objects fr...

if the object has not yet been moved
if the object has not yet been moved to the to-space, this is done by creating an identical copy in the to-space, and then replacing the from-space version with a forwarding pointer to the to-space copy. then update the object reference to refer to the new version in to-space.

the algorithm moves any white objects (equivalent to objects in the from-space without forwarding pointers) to the gray set by copying them to the to-space. objects that are between the scanning pointer and the free-space pointer on the to-space area are members of the gray set still to be scanned. objects below the sc...

the forwarding pointer (sometimes called a "broken heart")
the forwarding pointer (sometimes called a "broken heart") is used only during the garbage collection process; when a reference to an object already in to-space (thus having a forwarding pointer in from-space) is found, the reference can be updated quickly simply by updating its pointer to match the forwarding pointer.
