verifying that a variable, expression or value has the declared type
Questions on graph coloring, an assignment of colors to elements of a graph subject to specific constraints.
Questions about algorithms related to subsequences, or about properties of subsequences.
For questions about method for storing and manipulating numbers on computer systems, such as floating point or binary representations.
Questions related to mathematical analysis (often called analysis by mathematicians)
Questions about matters of computer, software and communication security, that is how to protect systems against attacks.
the study of relations (i.e., database tables) and relational operators (join, selection, projection, etc.) as a kind of algebraic structure.
used to transmit information through a noisy channel. They also have applications in theoretical computer science and combinatorics. Some well known error correcting codes a…
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.
For questions about the [assignment problem](https://en.wikipedia.org/wiki/Assignment_problem) in combinatorial optimization, **not** for problems that you've been set as a homework assignment.
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.

Questions related to general, high level, techniques for the design of algorithms.
LTL (linear temporal logic or linear-time temporal logic) is a temporal logic that can encode assertions about the future of traces.
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…
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.
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.
Scientific analysis of board games, playing strategies and their complexity
Questions about Hoare's logical framework for program correctness proofs and variants.
