An unsatisfactory property of particle filters is that they may become inefficient when the observation noise is low. In this paper we consider a simple-to-implement particle filter, called ‘LIS-based particle filter’, whose aim is to overcome the above mentioned weakness. LIS-based particle filters sample the particles in a two-stage process that uses information of the most recent observation, too. Experiments with the standard bearings-only tracking PROBLEM indicate that the proposed new particle filter method is indeed a viable alternative to other methods.

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the PROBLEM will simply be the sum of your scores for the individual test cases.

蟻群算法( ant colony algorithm) 是由意大利學者 Dorigo 等人[1 ,2 ] 于20 世紀90 年代初期通過模擬自然界 中螞蟻集體尋徑的行為而提出的一種基于種群的啟發 式仿生進化系統。蟻群算法包含兩個基本階段:適應階 段和協作階段。在適應階段,各候選解根據積累的信息 不斷調整自身結構。在協作階段,候選解之間通過信息 交流,以期望產生性能更好的解,這類似于學習自動機 的學習機制。蟻群算法最早成功應用于解決著名的旅 行商問題(t raveling salesman PROBLEM , TSP) ,該算法采 用了分布式正反饋并行計算機制,易于與其他方法結 合,而且具有較強的魯棒性[325 ] 。 蟻群算法創立十多年來,無論在算法理論還是在算 法應用方面都取得了很多突破性研究進展。

這是一個模擬第3類模式地震波的matlab腳本。 This a collection of Matlab scripts that solve the antiplane (mode III) earthquake dynamic PROBLEM with slip-weakening friction, on a 1D fault embedded in a 2D homogeneous elastic unbounded medium. The PROBLEM is formulated as a boundary integral equation and the elastodynamic kernels are analytically derived in the spectral domain (spatial wavenumber). The method is explained e.g. by Morrysey and Geubelle (1997), and has been improved and extensively used by Nadia Lapusta, Alain Cochard, etc.

Software developers need to have a number of traits in order to practice their craft well. First, they must be good analytical thinkers and PROBLEM solvers. A developer’s primary role is to create software that solves business PROBLEMs. This requires analyzing customer needs and coming up with successful, creative solutions.

As all of you know, MATLAB is a powerful engineering language. Because of some limitation, some tasks take very long time to proceed. Also MATLAB is an interpreter not a compiler. For this reason, executing a MATLAB program (m file) is time consuming. For solving this PROBLEM, Mathworks provides us C Math Library or in common language, MATLAB API. A developer can employ these APIs to solve engineering PROBLEMs very fast and easy. This article is about how can use these APIs.

所有的設計模式都有一些常用的特性：一個標識（a name），一個問題陳述（a PROBLEM statement）和一個解決方案(a solution)。 1、一個設計模式的標識是重要的，因為它會讓其他的程序員不用進行太深入的學習就能立刻理解你的代碼的目的（至少通過這個標識程序員會很熟悉這個模式）。? 2、問題描述是用來說明這個模式的應用的領域。? 3、解決方案描述了這個模型的執行。一個好的設計模式的論述應該覆蓋使用這個模型的優點和缺點。?
