Questions on graph coloring, an assignment of colors to elements of a graph subject to specific constraints.
Questions about memory-management techniques where the computer manages and transfers data between main memory and secondary storage in pages -- discrete chunks of a fixed size. Operating systems oft…

For questions about method for storing and manipulating numbers on computer systems, such as floating point or binary representations.
Questions about algorithms related to subsequences, or about properties of subsequences.
the study of relations (i.e., database tables) and relational operators (join, selection, projection, etc.) as a kind of algebraic structure.
Questions related to mathematical analysis (often called analysis by mathematicians)
the problem of finding groups of data points (often modelled as nodes in a graph) that are closer to each other than to other points.
Questions about matters of computer, software and communication security, that is how to protect systems against attacks.

Questions regarding solver programs for the boolean satisfiability problem.
a subset of the vertices of a graph such that every pair of vertices in the subset is connected by an edge.
off-topic here. Do not ask questions about how to write code in Java. However, conceptual questions about computer science are more appropriate. See our help center for the s…
a Last In First Out (LIFO) data structure. A common use of stacks is to store subroutine arguments and return addresses.
LTL (linear temporal logic or linear-time temporal logic) is a temporal logic that can encode assertions about the future of traces.
Requests for books covering a subject. Questions need to admit objective answers and identify a clear set of requirements or criteria for evaluating answers.
Questions about how to optimise a program's performance, both manually and automatically, e.g. in compilers.
Questions related to general, high level, techniques for the design of algorithms.
used to formalize mathematics and its concepts as a collection of objects and arrows (also called morphisms). Category theory can be used to formalize concepts of other high-level a…
Properties that hold before and after every execution of a loop. Used to prove correctness of algorithms.
