2. Cheney's algorithm - Wikipedia

   en.wikipedia.org/wiki/Cheney's_algorithm

   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.

3. Tracing garbage collection - Wikipedia

   en.wikipedia.org/wiki/Tracing_garbage_collection

   On the other hand, objects #5, #7, and #8 are not strongly referenced either directly or indirectly from the root set; therefore, they are garbage. In the naive mark-and-sweep method, each object in memory has a flag (typically a single bit) reserved for garbage collection use only.

4. Mark–compact algorithm - Wikipedia

   en.wikipedia.org/wiki/Mark–compact_algorithm

   The Compressor compaction algorithm [2] has the lowest complexity among compaction algorithms known today. It extends IBM’s garbage collection for Java. [ 3 ] The serial version of the Compressor maintains a relocation map that maps the old address of each object to its new address (i.e., its address before compaction is mapped to its address ...

5. 1-vs-2 cycles problem - Wikipedia

   en.wikipedia.org/wiki/1-vs-2_cycles_problem

   The 1-vs-2 cycles conjecture or 2-cycle conjecture is an unproven computational hardness assumption asserting that solving the 1-vs-2 cycles problem in the massively parallel communication model requires at least a logarithmic number of rounds of communication, even for a randomized algorithm that succeeds with high probability (having a ...

6. Garbage collection (computer science) - Wikipedia

   en.wikipedia.org/wiki/Garbage_collection...

   Garbage collection was invented by American computer scientist John McCarthy around 1959 to simplify manual memory management in Lisp. [3] Garbage collection relieves the programmer from doing manual memory management, where the programmer specifies what objects to de-allocate and return to the memory system and when to do so. [2]

7. Shunting yard algorithm - Wikipedia

   en.wikipedia.org/wiki/Shunting_yard_algorithm

   In computer science, the shunting yard algorithm is a method for parsing arithmetical or logical expressions, or a combination of both, specified in infix notation.It can produce either a postfix notation string, also known as reverse Polish notation (RPN), or an abstract syntax tree (AST). [1]

8. Garbage-first collector - Wikipedia

   en.wikipedia.org/wiki/Garbage-first_collector

   Garbage-first (G1) collector is a server-style garbage collector, targeted for multiprocessors with large memories, that meets a soft real-time goal with high probability, while achieving high-throughput. [2] G1 preferentially collects regions with the least amount of live data, or "garbage first". [3] G1 is the long term replacement of CMS.

9. Boehm garbage collector - Wikipedia

   en.wikipedia.org/wiki/Boehm_garbage_collector

   The Boehm–Demers–Weiser garbage collector, often simply known as the Boehm GC or Boehm collector, is a conservative garbage collector for C and C++ [1] developed by Hans Boehm, Alan Demers, and Mark Weiser. [2] [3] Boehm GC is free software distributed under a permissive free software licence similar to the X11 license. The first paper ...
