Good triangulations yield good tours [PDF]
, 2008 Consider the following heuristic for planar Euclidean instances of the traveling salesman problem (TSP): select a subset of the edges which induces a planar graph, and solve either the TSP or its graphical relaxation on that graph. In this paper, we give

Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Greedy Algorithms andM-Term Approximation with Regard to Redundant Dictionaries
, 1999 We study the efficiency of greedy type algorithms with regard to redundant dictionaries in Hilbert space and we prove a general result which gives a sufficient condition on a dictionary to guarantee that the pure greedy algorithm is near best in the ...

Greedy Algorithms and Rational Approximation in One and Several Variables [PDF]
, 2015 International audienceWe will review the recent development of rational approximation in one and several real and complex variables. The concept rational approximation is closely related to greedy algorithms, based on a dictionary consisting of Szeg˝ o ...

Greedy algorithms for image approximation from scattered Radon data
, 2021 Positive definite kernels are powerful tools for multivariate approximation from scattered data. This contribution discusses kernel-based image approximation from scattered Radon data. To this end, we use weighted kernels for the reconstruction. Moreover,

Advanced Functional Materials, EarlyView.A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,

Power allocation in cooperative sensor networks: a stochastic approximation approach
The Journal of Engineering, 2015 A power allocation technique based on simultaneous perturbation stochastic approximation is devised for wireless sensor networks. Power is such allocated in source and relay that at receiver the desired combined signal strength is attained. The behaviour
