Abstract
This paper describes a graph-theoretic complexity measure and illustrates how it can be used to manage and control program complexity. The paper first explains how the graph-theory concepts apply and gives an intuitive explanation of the graph concepts in programming terms. The control graphs of several actual Fortran programs are then presented to illustrate the correlation between intuitive complexity and the graph-theoretic complexity. Several properties of the graph-theoretic complexity are then proved which show, for example, that complexity is independent of physical size (adding or subtracting functional statements leaves complexity unchanged) and complexity depends only on the decision structure of a program.

Pair programming in education: a literature review

TL;DR: Research suggests that the benefits of pair programming include increased success rates in introductory courses, increased retention in the major, higher quality software, higher student confidence in solutions, and improvement in learning outcomes.

A software complexity model of object-oriented systems

TL;DR: The model defines the software complexity of OO systems at the variable, method, object, and system levels, and identifies measures that account for the cohesion and coupling aspects of the system.

Modern Coding Practices and Programmer Performance

TL;DR: The late 70' s find structured programming increasingly popular—this and other techniques are programming's future, but what does experimental evaluation say about their actual effects on programmer performance?

Measuring software design complexity

TL;DR: Based on a study of only eight medium-scale scientific projects, the data strongly support the value of the proposed complexity measure in this context and graphic representations of the software designs demonstrate structural differences corresponding to the results of the numerical complexity analysis.

An industrial study on the risk of software changes

TL;DR: A year-long study involving more than 450 developers of a large enterprise, spanning more than 60 teams, to better understand risky changes, i.e., changes for which developers believe that additional attention is needed in the form of careful code or design reviewing and/or more testing is conducted.

Structured Programming with go to Statements

TL;DR: For serious students of structured programming, and also for language designers, Knuth's "Structured Programming with go to Statements" is probably the paper to read.

Analysis of structured programs

TL;DR: It is shown that an arbitrary program P is reducible to a D-chart if and only if P does not contain a loop with two distinct exits.

A genealogy of control structures

TL;DR: It is argued further that there is insufficient evidence to warrant more than if-then-else, while-do, and their variants and the importance of one-in, one-out control structures as operational abstractions.
