TLDR
Several properties of the graph-theoretic complexity are proved which show, for example, that complexity is independent of physical size and complexity depends only on the decision structure of a program.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.read more

The evaluation of software systems' structure using quantitative software metrics
Sallie M. Henry,Dennis Kafura +1 more
TL;DR: This paper reports on a positive experience with a set of quantitative measures of software structure, which were used to evaluate the design and implementation of a software system which exhibits the interconnectivity of components typical of large‐scale software systems.

A probabilistic software quality model
TL;DR: This research aims at providing a probabilistic approach for computing high-level quality characteristics, which integrate expert knowledge, and deal with ambiguity at the same time, and shows that the quality model values change in accordance with the maintenance activities, and they are in a good correlation with the experts' expectations.

Test coverage and post-verification defects: A multiple case study
TL;DR: It is found that in both projects the increase in test coverage is associated with decrease in field reported problems when adjusted for the number of prerelease changes, which suggests that for most projects the optimal levels of coverage are likely to be well short of 100%.

One-way delay estimation using network-wide measurements
TL;DR: A novel approach for the estimation of one-way delays between network nodes without any time synchronization in the network is presented, and a second objective function that is based on the maximum-entropy (ME) principle is developed, considerably outperform the common method of halving the round-trip delays.

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.
