### Non-adaptive group testing on graphs with connectivity

Group testing refers to any procedure which groups arbitrary subsets of items into pools, and then tests each pool to identify the “sparse” defective items. This paper focuses on a probing scheme in non-adaptive group testing with graph-based …

### Skew-rank of an oriented graph and independence number of its underlying graph

An oriented graph $$G^\sigma$$ G σ is a digraph which is obtained by orienting every edge of a simple graph G, where G is called the underlying graph of $$G^\sigma$$ G σ . Let $$S(G^\sigma )$$ S ( G σ ) denote the skew-adjacency matrix of …

### On the randomized online strategies for the k-Canadian traveler problem

We consider the online k-Canadian Traveler Problem (k-CTP) which is defined on an undirected graph with a given source node O and a destination node D. Non-negative edge costs are given. The traveling agent is initially at O. There are k blocked …

### Online interval scheduling on two related machines: the power of lookahead

We consider an online interval scheduling problem on two related machines. If one machine is at least as twice as fast as the other machine, we say the machines are distinct; otherwise the machines are said to be similar. Each job $$j \in J$$ j ∈ …

### Model and algorithm of routes planning for emergency relief distribution in disaster management with disaster information update

Emergency relief distribution plays a vital role during disaster responding. This paper studies routes selection and transportation time moment selection for emergency relief distribution along with disaster information updating. This paper …
