19-letter words containing l, o, r, g, n
- register allocation — (compiler, algorithm) The phase of a compiler that determines which values will be placed in registers. Register allocation may be combined with register assignment. This problem can be shown to be isomorphic to graph colouring by relating values to nodes in the graph and registers to colours. Values (nodes) which must be valid simultaneously are linked by edges and cannot be stored in the same register (coloured the same). See also register dancing and register spilling.
- regression analysis — Statistics. a procedure for determining a relationship between a dependent variable, as predicted success in college, and an independent variable, as a score on a scholastic aptitude test, for a given population. The relationship is expressed as an equation for a line (regres·sion·line) or curve (regres·sion·curve) in which any coefficient (regression coefficient) of the independent variable in the equation has been determined from a sample population.

- relational language — (language) Any kind of programming language that specifies output in terms of some property and some arguments. For example, if Tom has two brothers, Dick and Harry, a relational language will respond to the query "Who is Tom's brother?" with either Dick or Harry.

- run-length encoding — A kind of compression algorithm which replaces sequences ("runs") of consecutive repeated characters (or other units of data) with a single character and the length of the run. This can either be applied to all input characters, including runs of length one, or a special character can be used to introduce a run-length encoded group. The longer and more frequent the runs are, the greater the compression that will be achieved. This technique is particularly useful for encoding black and white images where the data units would be single bit pixels.
