TLDR
A decision tree-like model for defining and measuring the on-line complexity of algorithms for generating combinatorial objects is developed and the amount of data structure update required to generate the successor to a given codeword is emphasized.
Abstract
The purpose of this paper is to develop a decision tree-like model for defining and measuring the on-line complexity of algorithms for generating combinatorial objects. For the purpose of illustration, we consider the problem of generating Gray codes and simple generalizations of Gray codes. We include some results pertaining to the generation of certain special codes and, in addition, we present a trade-off theorem. Our model is information theoretical and we emphasize two aspects of complexity; the amount of information that must be gathered and the amount of data structure update required to generate the successor to a given codeword.

Complexity models for incremental computation

TL;DR: This work defines complexity classes that capture the intuitive notion of incremental efficiency and study their relation to existing complexity classes and shows that problems that have small sequential space complexity also have small incremental time complexity.

The Complexity of Maintaining an Array and Computing Its Partial Sums

TL;DR: A trade-off between the complexmes of (a) versus (b) is observed, and the informatlon-theoreuc complexity measure counts the number of accesses and changes to a random access memory.

Lower bounds for union-split-find related problems on random access machines

TL;DR: This work proves Ω(√log log n) lower bounds on the random access machine complexity of several dynamic, partially dynamic and static data structure problems, including the union-split-find problem, dynamic prefix problems and one-dimensional range query problems.
