计算机是现代社会中用于解决问题的重要工具。利用计算机解决实际问题需要将问题抽象，并对数据进行操作，最后通过计算机程序求解问题。而本门课程主要内容就是对以上内容进行研究。

图灵奖获得者N.Wirth写了一本经典著作“程序=算法+数据结构”。数据结构，是抽象的表示数据的方式；算法，则是计算的一系列有效、通用的步骤。算法与数据结构是程序设计中相辅相成的两个方面。

我 们会围绕着“算法+数据结构=程序”的思路，以问题求解为导向进行学习。希望能够帮助大家提高理论、抽象、设计的能力。在扎实的经典理论基础上，运用问题 抽象、数据抽象、算法抽象来分析问题，应用适当的数据结构和算法来设计和实现相应的程序。通过课程学习，大家的抽象思维能力、问题求解能力将得到较大提 升，编程能力和代码质量会有质的飞跃！

在求解实际问题方面，我们会学习到通过权衡时空和其他资源开销，利用数据结构来组织数据、设计高效的算法、完成高质量的程序以满足错综复杂的实际应用需要。

此外，课程所学到的内容会被利用到计算机科学后续的各个课程中，如操作系统、软件工程、数据库概论、编译技术、计算机图形学、人机交互等。希望可以为大家将来从事计算机相关的学习、研究和开发工作打下扎实的基础。

本课程采用张铭主编的国家“十一五”规划教材《数据结构与算法》（高等教育出版社）。适合计算机以及相关理工专业的大二本科生学习，需要先修过计算概论等课程，具有结构化和面向对象的程序设计基础。

课程主要包括的内容有：线性表，栈与队列，字符串，二叉树，树，图，排序（内排序，外排序），检索，索引，高级数据结构、以及数据结构应用。课程持续16周（分为两个session，每个8周），学习者每周在本课程上需要投入4－8小时。

Computers are an important tool for problem solving and are deeply involved in modern life. Computers perform operations on data. What is the logical relationship among data? How is data stored in computers? What algorithms are required to solve particular problems? These are the questions that will be answered in “Data Structures and Algorithms,” an important core course in Computer Science. The course also introduces students to fundamental data structures and classical algorithms used in more specialized courses, including Operating Systems, Software Engineering, Database Systems, Compiler Principles, Computer Graphics and Human Computer Interaction.

Niklaus Wirth described the important and indivisible link between algorithms and data structure in his book, Algorithms + Data Structures = Programs.

The course will build on Wirth’s ideas as it helps students improve their knowledge of theory and their ability to think abstractly to solve problems. Building on a solid theoretical foundation, students will analyze problems using data and algorithm abstraction. Students will learn how to organize data efficiently and make tradeoffs between space and time complexity, design efficient and effective algorithms, and implement high quality programs to solve complex real-world problems. After studying this course, students will be well prepared for further study and research in engineering and other computer-related areas.

This is an intermediate-level course appropriate for sophomore students majoring in computer science or other science/engineering disciplines. Students should have learned "introduction to computing", with the knowledge of structured and object-oriented programming.

This course is presented in two eight-week sessions.

Students who score 60% or higher will receive an Honor Code Certificate.

The Autumn 2014 Sessions of this course are supported by Google.

课程采用的算法语言? Which programming languages does the course use?

本课程采用基于C++的伪代码授课和出习题。编程作业是POJ自动评判的，该平台目前接受 C、C++、Java等都可以。

The course’s content and exercises are both based upon C++ pseudo code. Programming assignments are automatically assessed by POJ which accepts code written in C/C++ and JAVA.

Oddly enough, the contribution of behavioral science to helping people deal with dog behavioral problems and train dogs has only been modest. In this course, we will explore modern approaches to dog behavioral problems and training that incorporate the latest findings from behavioral science.

We will cover the use of behavioral functional analysis to:

• uncover the causes of undesired behavior
• explore just what it is about humans that dogs find reinforcing
• critically evaluate different approaches to dog training
• survey the use of temperament tests to assess the suitability of dogs for different roles

This course is part of the Dog Behavior and Cognition XSeries.

This course is approved for CEUs by the following organizations:

• Certification Council for Professional Dog Trainers (CCPDT)
  • Students who pass will receive a certificate for a total of 6 CEUs for behavior consultants. Additional CEUs are available by taking the remaining two courses in the series: Dog Origins (7 CEUs) and Dog Perception and Cognition (7.5 CEUs).
• International Association of Animal Behavior Consultants (IAABC)
  • Students who pass will receive a certificate for a total of 5.375 CEUs. Additional CEUs are available by taking the remaining two courses in the series: Dog Origins (6.125 CEUs) and Dog Perception and Cognition (6.5 CEUs).

  • Students who pass will receive a certificate for a total of 3.0 CEUs. Additional CEUs are available by taking the remaining two courses in the series: Dog Origins (3.5 CEUs) and Dog Perception and Cognition (3.5 CEUs).

The origin of dogs is shrouded in mystery. In this course, you will learn how to interpret the often contradictory ideas about how, why, where and when dogs arose.

Geneticists, archaeologists, anthropologists and behavioral scientists offer a variety of often opposing ideas about how dogs—the first domesticated species—arose. Some place the origin of dogs over 100,000 years ago; others place the start of dogs just 12,000 years ago. Claims for the location of the origin of dogs range from China to Europe and many places in between. Diverse scholars have suggested dogs arose as trash scavengers or as hunters’ helpers.

This course will provide you with the tools you need to find your own way through the confusing claims about the origin of dogs.

This course is part of the Dog Behavior and Cognition XSeries. 

No previous knowledge of any of the sciences contributing to the origins of dogs is assumed. Form your own assessment of the mysterious origins of “man’s best friend.”

This course is approved for CEUs by the following organizations:

Many natural and man-made structures can be modeled as assemblages of interconnected structural elements loaded along their axis (bars), in torsion (shafts) and in bending (beams). In this course you will learn to use equations for static equilibrium, geometric compatibility and constitutive material response to analyze these structural assemblages.

This course also provides an introduction to behavior in which the shape of the structure is permanently changed by loading the material beyond its elastic limit (plasticity), and behavior in which the structural response changes over time (viscoelasticity).

This is the second course in a 3-part series. In this series you will learn how mechanical engineers can use analytical methods and “back of the envelope” calculations to predict structural behavior.  The three courses in the series are:

Part 1 – 2.01x: Elements of Structures. (Elastic response of Structural Elements: Bars, Shafts, Beams). Next session starts October 2017

Part 2 – 2.02.1x Mechanics of Deformable Structures: Part 1. (Assemblages of Elastic, Elastic-Plastic, and Viscoelastic Structural Elements).

 Part 3 – 2.02.2x Mechanics of Deformable Structures: Part 2. (Multi-axial Loading and Deformation. Energy Methods). Next session starts October 2018

These courses are based on the first subject in solid mechanics for MIT Mechanical Engineering students.  Join them and learn to rely on the notions of equilibrium, geometric compatibility, and constitutive material response to ensure that your structures will perform their specified mechanical function without failing.
