Pebble game rigidity analysis is an efficient method for extracting rigidity and flexibility information of biomolecules without performing costly molecular dynamics simulations. The standard algorithm works on a multi-graph associated to a mechanical model constructed from an arbitrary atom-bond network. Motivated by large scale protein flexibility and simulated unfolding applications, we have developed...
The paper considers a new method of the Quality of Service (QoS) assurance in opportunistic access to wireless networks using a game theoretic-framework. The perfect full information of the involved links is made known to the central management unit called spectrum broker. Three algorithms of spectrum sharing are proposed. In each algorithm, Cournot oligopoly competition or monopolistic behaviour...
Markets of computing resources typically consist of a cluster (or a multi-cluster) and jobs that arrive over time and request computing resources in exchange for payment. In this paper we study a real system that is capable of preemptive process migration (i.e. moving jobs across nodes) and that uses a market-based resource allocation mechanism for job allocation. Specifically, we formalize our system...
In the environment of e-market, based on the Stackelberg game, the stochastic expectation model of supply chain option contract coordination with random demand, random market price and market access degree is established in this paper. As the leader, the supplier declares the optimal contract reservation costs and execution costs for maximizing his expected profit, while as the follower, the purchaser...
This paper presents a coevolutionary algorithm named cooperative coevolutionary invasive weed optimization (CCIWO) and investigates its performance for global optimization of functions with numerous local optima and also Nash equilibrium (NE) search for games. Ability of CCIWO for function optimization is tested through a set of common benchmarks of stochastic optimization, and reported results are...
This paper addresses the location problem in emergency management with some constraints. Let G = (V, E) be an undirected graph with positive edge lengths and positive vertex weights. The traditional location problem in emergency management is to locate p facilities on vertices of G such that the sum of the weighted distances of the vertices to the closest facility is minimized. This paper improves...
With the development of Chinese economy, more and more large planned special events, such as Olympic Games, Expo, and so on, have been held in many metropolitans, which may bring huge pressures to city's normal transportation. In this paper, a non-equilibrium vehicle evacuation model at small area under planned special events was set up, and the heuristic algorithm was given in detail. Then, we applied...
When a paid price discount activity occurs, the decision-maker must decide whether or not and when to pay the additional fees for preferential price in an online fashion. This problem which generalizes the basic leasing problem has been introduced and studied by Fleischer et al. In this paper, we extend the basic model to consider different price discount replacement case and present the optimal deterministic...
The proxy chain-like alliance is important management and the basic business model of the plant expansion scale effect. To various proxy to link the bracelet enterprise which are the allies joining in the chain-like main body core enterprise, how to support the rate policy-making decision aided by the management science and the information technology is a development strategic decision question for...
The discrete network design problem deals with the selection of link additions to an existing road network, with given demand from each origin to each destination. The objective is to make an optimal investment decision in order to minimize the total travel cost in the network, while accounting for the route choice behaviors of network users. The discrete network design problem is considered as a...
The aim of load matching at truck is to make the truck cargo stowage reasonable in volume, weight and loading sequence of a distribution area, to raise efficiency of truck and to reduce costs of the distribution. An effectual truck stowage planning model is built. The model can equilibrate the truck cargo weight and the volume and make the transport resources more effective. The opinion of backtrack...
Pattern recognition provides solution to many problems in real life such as in biometric system, personal identification of banks etc. It matches two point sets and consequently identify if they are identical. This is applicable in fingerprint recognition with minutiae as a representation, which has been widely used as an individual identification method. Fingerprint recognition is divided into two...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
We present a distributed learning algorithm for optimising transit prices in a negotiation problem in the inter-domain routing framework. We present a combined game theoretic and distributed algorithmic analysis, where the notion of Nash equilibrium with the first approach model meets the notion of stability in the second. We show that minimum cost providers can learn how to strategically set their...
