Web23 okt. 2009 · The big difference between mark-copy and mark-sweep-compact is that the former copies to a separate space, and the latter moves to a different part of the same space. This significantly affects the implementation; e.g. use of the old space to hold forwarding pointers. In computer science, a mark–compact algorithm is a type of garbage collection algorithm used to reclaim unreachable memory. Mark–compact algorithms can be regarded as a combination of the mark–sweep algorithm and Cheney's copying algorithm. First, reachable objects are marked, then a compacting step relocates the reachable (marked) objects towards the beginning of the heap area. Compacting garbage collection is used by modern JVMs, Microsoft's Common Language R…
