Although some computer scientists only know how to prove things by induction, this isn’t true of everyone. The best sometimes use contradiction.
The basic scheme of a contradiction argument is as follows:

• Assume that the hypothesis (the statement you want to prove) is false.
• Develop some logical consequences of this assumption.
• Show that one consequence is demonstrably false, thereby showing that the assumption is incorrect and the hypothesis is true.

The classic contradiction argument is Euclid’s proof that there are an infinite number of prime numbers: integers $n$ like $2,3,5,7,11, \ldots$ that have no nontrivial factors, only 1 and $n$ itself. The negation of the claim would be that there are only a finite number of primes, say $m$, which can be listed as $p_1, \ldots, p_m$. So let’s assume this is the case and work with it.

Prime numbers have particular properties with respect to division. Suppose we construct the integer formed as the product of “all” of the listed primes:
$$N=\prod_{i=1}^m p_i$$
This integer $N$ has the property that it is divisible by each and every one of the known primes, because of how it was built.

But consider the integer $N+1$. It can’t be divisible by $p_1=2$, because $N$ is. The same is true for $p_2=3$ and every other listed prime. Since $N+1$ doesn’t have any non-trivial factor, this means it must be prime. But you asserted that there are exactly $m$ prime numbers, none of which are $N+1$. This assertion is false, so there cannot be a bounded number of primes. Touché!

For a contradiction argument to be convincing, the final consequence must be clearly, ridiculously false. Muddy outcomes are not convincing. It is also important that this contradiction be a logical consequence of the assumption. We will see contradiction arguments for minimum spanning tree algorithms in Section 8.1.

## 统计代写|算法设计代写Algorithm Design代考|About the War Stories

The best way to learn how careful algorithm design can have a huge impact on performance is to look at real-world case studies. By carefully studying other people’s experiences, we learn how they might apply to our work.

Scattered throughout this text are several of my own algorithmic war stories, presenting our successful (and occasionally unsuccessful) algorithm design efforts on real applications. I hope that you will be able to internalize these experiences so that they will serve as models for your own attacks on problems.
Every one of the war stories is true. Of course, the stories improve somewhat in the retelling, and the dialogue has been punched up to make them more interesting to read. However, I have tried to honestly trace the process of going from a raw problem to a solution, so you can watch how this process unfolded.
The Oxford English Dictionary defines an algorist as “one skillful in reckonings or figuring.” In these stories, I have tried to capture some of the mindset of the algorist in action as they attack a problem.

The war stories often involve at least one problem from the problem catalog in Part II. I reference the appropriate section of the catalog when such a problem occurs. This emphasizes the benefits of modeling your application in terms of standard algorithm problems. By using the catalog, you will be able to pull out what is known about any given problem whenever it is needed.

• 假设假设（您要证明的陈述）是错误的。
• 发展这个假设的一些逻辑后果。
• 证明一个结果显然是错误的，从而表明假设是不正确的，而假设是正确的。

《牛津英语词典》将算法学家定义为“善于计算或计算的人”。在这些故事中，我试图捕捉算法学家在解决问题时的一些思维方式。
