However finding a Shortest Double stranded DNA string (SDDNA) containing all the .-long words in the reads seems to be a good heuristic to get close to the original genome. This problem is equivalent to finding a cyclic Chinese Postman (CP) walk on

Lecture Notes in Computer Scienceny large-scale real networks creates a belief that it may be easier to solve many optimization problems in such networks. Our works focus on the hardness and inapproximability of optimization problems on power law graphs (PLG). In this paper, we show that the ., . and . are still .-hard on power law

From New Technologies to New Solutionses. The cardinality of a minimum cyclic vertex-cut of ., denoted by ..(.), is the cyclic vertex-connectivity of .. In this paper, we show that for any integer . ≥ 4, the .-dimensional star graph .. has ..(..) = 6(. − 3).

This result generalizes a previous one for the star graph, and can be applied to obtain the number of the shortest paths between a pair of vertices in some of the other similar structures. It also implies an algorithm to enume

Friendly Observers Ease Off-Line E-Cashogramming to formulate GPP and CNP. In several practice cases, we have networks with uncertain weights of links. Some times, these uncertainties have no information of probability distribution. We use robust optimization models of GPP and CNP to formulate the community structures or influential individuals in such networks.
