Vehicle Routing Problem with Time Windows(abbr. VRPTW) was mainly researched in this paper. Proven to be a NP-hard problem, it was difficult to get the exact solutions to VRPTW with numerous nodes.
本文着重研究有时间窗的车辆路径问题(Vehicle Routing Problem with Time Windows, VRPTW),VRPTW现已被证明为NP-hard问题,当问题规模较大时,将很难得到问题的精确解。
An intelligence sale system for motorbike accessories is designed and implemented using BDE engine, C++ builder,C++,SQL at Windows 98 SE platform. The system comprises modules of sale, clients, goods and statistic graphs.
For a fairly general class of orthonormal scaling functions and wavelets with regularity exponents n, we prove that the areas of the time-frequency windows tend to infinity as n → ∞.
When, in addition, the Tolimieri-Orr condition A is satisfied, the minimum energy dual windowoγ ε L2(?) can be sampled as well, and the two sampled windows continue to be related by duality and minimality.
Characterization and Computation of Canonical Tight Windows for Gabor Frames
Iterative Algorithms to Approximate Canonical Gabor Windows: Computational Aspects
We consider two strategies for scaling the terms in the iteration step: Norm scaling, where in each step the windows are normalized, and initial scaling where we only scale in the very beginning.
