LinearTime Algorithms in Memory Hierarchies
"... This paper studies lineartime algorithms on a hierarchical memory model called Block Move (BM), which extends the Block Transfer (BT) model of Aggarwal, Chandra, and Snir, and which is more stringent than a pipelining model studied recently by Luccio and Pagli. Upper and lower bounds are shown for ..."

On lineartime algorithms for fivecoloring planar graphs
 Inform. Process. Lett
, 1984
"... Certain properties of planar graphs are established in a particularly straightforward fashion. These properties assure good performance in two lineartime algorithms for fivecoloring planar graphs. A new lineartime algorithm, based on a third property, is also presented. Keywords: Graph coloring, ..."

LinearTime Algorithms for the Multiple Gene Duplication Problems
 IEEE Trans. Computational Biology and Bioinformatics
, 2011
"... Abstract—A fundamental problem arising in the evolutionary molecular biology is to discover the locations of gene duplications and multiple gene duplication episodes based on the phylogenetic information. The solutions to the MULTIPLE GENE DUPLICATION problems can provide useful clues to place the g ..."

Linear time algorithms for Clobber
, 2007
"... We prove that the singleplayer game clobber is solvable in linear time when played on a line or on a cycle. For this purpose, we show that this game is equivalent to an optimization problem on a set of words defined by seven classes of forbidden patterns. We also prove that, playing on the cycle, i ..."

It should be noticed that the algorithms which compute the Shortest Path and Minimum Spanning Tree problems not only analyze the weight of arcs (which is the main and often the only criterion of solution hitherto known algorithms) but also in case of identical path
A Lineartime Algorithm for Sparsification . . .
"... Given an undirected graph G and an error parameter ε> 0, the graph sparsification problem requires sampling edges in G and giving the sampled edges appropriate weights to obtain a sparse graph Gε with the following property: the weight of every cut in Gε is within a factor of (1 ± ε) of the weigh ..."

) of the weight of the corresponding cut in G. If G is unweighted, an O(mlogn)time algorithm for constructing Gε with O(nlogn/ε²) edges in expectation, and an O(m)time algorithm for constructing Gε with O(nlog² n/ε²) edges in expectation have recently been developed [9]. In this paper, we improve these results
Constructive Linear Time Algorithms for Branchwidth

A Simple Linear Time Algorithm for . . .
"... A circulararc model M = (C, A) is a circle C together with a collection A of arcs of C. If no arc is contained in any other then M is a proper circulararc model, and if some point of C is not covered by any arc then M is an interval model. A (proper) (interval) circulararc graph is the intersecti ..."

Linear time recognition algorithms have been described both for the general class and for some of its subclasses. For the isomorphism
