The simplest search strategy is the sequential search (table scan), in which the database system searches through the entire table, row-by-row. However, for large quantities of data, the sequential search is often the most complex and expensive search strategy. The database system uses the se...
Sequential Consumer SearchOligopolyPrice DispersionThis note explores asymmetries in the way consumers sample prices in a simple variation of Stahl's (1989) seminal model of sequential search. In the note, we cdoi:10.2139/ssrn.1622809Astorne-Figari, Carmen...
a sequential search, also known as a linear search, is a method for finding a particular value in a list. it works by starting at the beginning of the list and comparing each element with the target value until it's found or until all elements have been checked. when would i want to...
We study the performance of heuristics relative to the performance of optimal solutions in the rich domain of sequential search, where the decision to stop the search depends only on the applicant’s relative rank. Considering multiple variants of the secretary problem, that vary from one another ...
Many everyday decisions require sequential search, according to which available choice options are observed one at a time, with each observation involving some cost to the decision maker. In these tasks, decision makers need to trade-off the chances of finding better options with the cost of sea...

The last part of the paper is devoted to purely algorithmic optimization of the correspondence search; this allows for a significant speed-up of the computation. The source code is available for download. CCF-B 370 被引用 · 13 笔记 引用 Global Hough localization for mobile robots in ...
This repositary is a combination of different resources lying scattered all over the internet. The reason for making such an repositary is to combine all the valuable resources in a sequential manner, so that it helps every beginners who are in a search
牛顿法求解的过程要保证黑森矩阵是正定矩阵这样才是正确的收敛方向,所以要加一个阻尼系数H=H+rho*I, I是单位矩阵,rho是阻尼系数,这其实就是damp-newton method,他后面一堆操作和方法都是保证收敛方向是向着极小值,外面的line search方法就是是梯度下降,本质上找一个最优的alpha使得L对alpha偏导为0,操作上一般...
