If a transit vehicle breaks down on a schedule trip, there are some vehicles in the system need to serve this trip and the former plan must be changed. For solving the urgency vehicle routing problem with disruption that may be vehicle breakdowns or traffic accidents in the logistics distribution system, through the analysis of the problem and the disruption measurement, the mathematics model i...

In Ref.1, extremum problems having in nite-dimensional image have been considered and some preliminary properties have been established. Here we carry on the investigation of such problems and study an optimality condition for the case of unilateral constraints, which partially extends the results of [2,3] to the present type of problems. This is done by associating to the feasible set a specia...

A rate-distortion model for describing the motion prediction efficiency in interframe wavelet video coding is proposed in this paper. Different from the non-scalable video coding, the scalable wavelet video coding needs to operate under multiple bitrate conditions and it has an open-loop structure. The conventional Lagrangian multiplier, which is widely used to solve the rate-distortion optimiz...

Abstract Because the current computer sensor data positioning analysis has difficulties and false problems, we use Lagrangian multiplier method of interactive direction to disassemble sound source. Through this algorithm, information fusion nodes is realized. After using mathematical equations, these error correction measurements have achieved better target results. Theoretical experimental res...

Abstract We propose a robust and efficient augmented Lagrangian-type preconditioner for solving linearizations of the Oseen–Frank model arising in nematic cholesteric liquid crystals. By applying Lagrangian method, Schur complement director block can be better approximated by weighted mass matrix Lagrange multiplier, at cost making harder to solve. In order solve block, we develop multigrid alg...

Solution oscillations, often caused by identical solutions to the homogeneous subproblems, constitute a severe and inherent disadvantage in applying Lagrangian relaxation based methods to resource scheduling problems with discrete decision variables. In this paper, the solution oscillations caused by homogeneous subproblems in the Lagrangian relaxation framework are identified and analyzed. Bas...

for all x ∈ IR, λ ∈ IR, μ ∈ IR +. PHR-based Augmented Lagrangian methods for solving (1) are based on the iterative (approximate) minimization of Lρ with respect to x ∈ Ω, followed by the updating of the penalty parameter ρ and the Lagrange multipliers approximations λ and μ. The most popular practical Augmented Lagrangian method gave rise to the Lancelot package [24, 25, 26]. Lancelot does not...

1 Datasets description Ten heterogeneous relational data sources having direct or indirect relevance toward lncRNA-disease association are collected for experiments. The sources of these data sources and statistics of these data sources are listed in Table S1 and Table S2. 2 Optimizing G, S and W This section elaborates on how to iteratively optimize G, S and W in the objective function of MFLD...
