某石油公司计划建造一条由东向西的主输油管道。该管道要穿过一个有 n 口油井的油田。从每口油井都要有一条输油管道沿最短路经(或南或北)与主管道相连。如果给定 n口油井的位置,即它们的 x 坐标（东西向）和 y 坐标（南北向）,应如何确定主管道的最优位置,即使各油井到主管道之间的输油管道长度总和最小的位置?证明可在线性时间内确定主管道的最优位置,使得给定n口油井的位置,编程计算各油井到主管道之间的输油管道最小长度总和。 -An oil company plans to construct a east to west from the main pipeline. The pipeline to pass through an oil field n wells. Wells from each must have a pipeline along the shortest path (or South or North) connected with the competent Road. If given the location of oil wells in n, that is, their x coordinates (east-west) and y coordinates (north-south), should be how to determine the optimal position in charge of Road, even if the wells to the pipeline in charge of Road between the sum of the smallest length location? proved to be linear time in charge of Road to determine the optimal location, making a given n the location of oil wells, programmed to calculate the well-to-charge of Road between the length of the sum of the smallest oil pipeline.

This book is the product of a twenty-year resarch project at Rice University to develop fundamental compiler technologies for vector and parallel computer systems. The effort was by Randy Allen and Ken Kennedy with the help of David Kuck and Michael Wolfe.

本书真实系统地介绍了密码学及该领域全面的参考文献。 全书共分四个部分，首先定义了密码学的多个术语，介绍了密码学的发展及背景，描述了密码学从简单到复杂的各种协议，详细讨论了密码技术，并在此基础上列举了如DES、IDEA、RSA、DSA等10多个算法以及多个应用实例，并提供了算法的源代代码清单。 全书内容广博权威，具有极大的实用价值。自出版以来，得到业内专家的高度赞誉，是致力于密码学研究的专业及非专业人员一本难得的好书。-This book introduces the real system and the field of cryptography comprehensive references. Book is divided into four parts, first of all define the term more than cryptography, introduced the development of cryptography and background, describes cryptography from the simple to the complex variety of the agreement, a detailed discussion of cryptographic techniques, and on this basis cited, such as DES, IDEA, RSA, DSA algorithm, as well as more than 10 examples of multiple applications and provides the algorithm source code on behalf of the list. Broad authority of the contents of the book, has great practical value. Self-publishing has been highly praised the industry experts, is dedicated to the study of cryptography professional and non-professional a rare book.
