Nondeterministic time and space complexity classes by Joel Irvin Seiferas ( Book )
3 editions published in 1974 in English and held by 15 WorldCat member libraries worldwide
Two heads are better than two tapes by Tao Jiang ( Book )
5 editions published in 1994 in English and held by 14 WorldCat member libraries worldwide
Abstract: "We show that a Turing machine with two single-head one-dimensional tapes cannot recognize the set [x2x' / x [member of] [0,1][superscript *] and x' is a prefix of x] in real time, although it can do so with three tapes, two two-dimensional tapes, or one two-head tape, or in linear time with just one tape. In particular, this settles the longstanding conjecture that a two-head Turing machine can recognize more languages in real time if its heads are on the same one-dimensional tape than if they are on separate one-dimensional tapes."
Counting is easy by Joel Irvin Seiferas ( Book )

A tight lower bound for on-line monotonic list labeling by Paul Frederick Dietz ( Book )

Bits and relative order from residues, space efficiently by Paul Frederick Dietz ( Book )
2 editions published in 1993 in English and held by 4 WorldCat member libraries worldwide
A note on almost-everywhere-complex sets and separating deterministic-time-complexity classes by John G Geske ( Book )
1 edition published in 1989 in English and held by 3 WorldCat member libraries worldwide
A variant of Ben-Or's lower bound for algebraic decision trees by Joel Irvin Seiferas ( Book )
1 edition published in 1987 in English and held by 3 WorldCat member libraries worldwide
Abstract: "Ben-Or's lower bound on the height of a fixed-degree algebraic decision tree to decide membership in a set is based on the number of connected components in the set. A similar bound holds based on the sometimes much larger number of connected components in the interior of the set."
An [Omega](n log n) lower bound for a restricted form of on-line labeling algorithm by J Zhang ( Book )
1 edition published in 1989 in English and held by 2 WorldCat member libraries worldwide
Abstract: "Under the Normalization Assumption on the algorithms, the labeling problem has a lower bound [Omega](n log n). This is proved by a mechanism dividing the label intervals into lists of collections whose corresponding costs are bounded from below by a suitably chosen function."
Observational complexity of character strings by Joel Irvin Seiferas ( Book )
1 edition published in 1972 in English and held by 1 WorldCat member library worldwide
Time-space-optimal string matching : preliminary report by University of Rochester ( Book )
1 edition published in 1981 in English and held by 1 WorldCat member library worldwide
An information-theoretic approach to time bounds for on-line computation preliminary version by Wolfgang J Paul ( )
