Why do you think it is the case? But should this preclude granting patents for all algorithms? You may assume that you are writing your algorithms for a human rather than a machine. Still, make sure that your descriptions do not contain obvious ambiguities. Knuth provides an interesting comparison between cooking recipes and algorithms [KnuI,p. Just follow Euclid's algorithm as described in the text.

Compare the number of divisions made by the two algorithms. Of course, for some coefficients, the equation will have no solutions. Al-Khwarizmi 9th century C. In fact, the word "algebra" is derived from the Arabic title of this book while the word "algorithm" is derived from a translation of Al-Khwarizmi's last name see, e.

This legal issue has yet to be settled. The current legal state of affairs distinguishes mathematical algorithms, which are not patentable, from other algorithms, which may be patentable if implemented as computer programs e.

The answer will be the number's immediate predecessor. Note: A much faster algorithm for solving this problem can be obtained by using Newton's method see Sections Initialize the list of common elements to empty.

Starting with the first elements of the lists given, repeat the following until one of the lists becomes empty. Compare the current elements of the two lists: if they are equal, add this element to the list of common elements and move to the next elements of both lists if any ; otherwise, move to the element following the smaller of the two involved in the comparison.

To answer the question, we need to compare the number of divisions the algorithms make on the input given. The number of divisions made by Euclid's algorithm is 11 see part a. It is not too difficult to prove that the integers that can be written on the board are the integers generated by the subtraction version of Euclid's algorithm and only them. Since all the doors are initially closed, a door will be open after the last pass if and only if it is toggled an odd number of times.

Old World puzzle A peasant finds himself on a riverbank with a wolf, a goat, and a head of cabbage. He needs to transport all three to the other side of the river in his boat. However, the boat has room for only the peasant himself and one other item either the wolf, the goat, or the cabbage. In his absence, the wolf would eat the goat, and the goat would eat the cabbage. Solve this problem for the peasant or prove it has no solution.

Note: The peasant is a vegetarian but does not like cabbage and hence can eat neither the goat nor the cabbage to help him solve the problem. And it goes without saying that the wolf is a protected species. New World puzzle There are four people who want to cross a rickety bridge; they all begin on the same side.

You have 17 minutes to get them all across to the other side. It is night, and they have one flashlight. A maximum of two people can cross the bridge at one time. Any party that crosses, either one or two people, must have the flashlight with them. The flashlight must be walked back and forth; it cannot be thrown, for example. Person 1 takes 1 minute to cross the bridge, person 2 takes 2 minutes, person 3 takes 5 minutes, and person 4 takes 10 minutes. A pair must walk together at the rate of the slower person's pace.

Note: According to a rumor on the Internet, interviewers at a well-known software company located near Seattle have given this problem to interviewees. Describe the algorithm used by your favorite ATM machine in dispensing cash.

You may give your description in either English or pseudocode, whichever you find more convenient. How many instances does this problem have?

Look up an algorithm for this problem on the Internet. Give an example of a problem other than computing the greatest common divisor for which you know more than one algorithm. Which of them is simpler? Which is more efficient? Consider the following algorithm for finding the distance between the two closest elements in an array of numbers. If you need to, you may change the algorithm altogether; if not, improve the implementation given.

Find this summary on the Internet or, better yet, in his book, and compare it with the plan outlined in Section 1. What do they have in common? How are they different? The peasant would have to make several trips across the river, starting with the only one possible. Unlike the Old World puzzle of Problem 1, the first move solving this puzzle is not obvious. The principal issue here is a possible ambiguity.

Your algorithm should work correctly for all possible values of the coefficients, including zeros. You almost certainly learned this algorithm in one of your introductory programming courses. If this assumption is not true, you have a choice between designing such an algorithm on your own or looking it up. You may need to make a field trip to refresh your memory. Question a is difficult, though the answer to it-discovered in s by the German mathematician Johann Lambert -is well-known.

By comparison, question b is incomparably simpler. You probably know two or more different algorithms for sorting an array of numbers. You can: decrease the number of times the inner loop is executed, make that loop run faster at least for some inputs , or, more significantly, design a faster algorithm from scratch.

Let P, w, g, and c stand for the peasant, wolf, goat, and cabbage head, respectively. The following is one of the two principal sequences that solve the problem: Note: This problem is revisited later in the book see Section 6. The formula can be considered an algorithm if we assume that we know how to compute the square root of an arbitrary positive number. This is true even if we assume, as we did for the square root function, that we know how to compute the sine of a given angle.

There are several algorithms for doing this but only approximately, of course. With this interpretation, the problem has infinitely many instances. Understand the problem 2.

Devise a plan 3. Implement the plan 4. Apply this algorithm to sorting the list 60, 35, 81, 98, 14, Is this algorithm stable? Is it in place?

Name the algorithms for the searching problem that you already know. Give a good succinct description of each algorithm in English. If you know no such algorithms, use this opportunity to design one. Design a simple algorithm for the string-matching problem. It was solved by the great Swiss-born mathematician Leonhard Euler Following is a sketch of the river with its two islands and seven bridges:a.

State the problem as a graph problem. Does this problem have a solution? If you believe it does, draw such a stroll; if you believe it does not, explain why and indicate the smallest number of new bridges that would be required to make such a stroll possible. Icosian Game A century after Euler's discovery see Problem 4 , another famous puzzle-this one invented by the renown Irish mathematician Sir William Hamilton -was presented to the world under the name of the Icosian Game.

The game was played on a circular wooden board on which the following graph was carved:Find a Hamiltonian circuit-a path that visits all the graph's vertices exactly once before returning to the starting vertex-for this graph. Consider the following problem: Design an algorithm to determine the best route for a subway passenger to take from one designated station to another in a well-developed subway system similar to those in such cities as Washington, D.

The problem's statement is somewhat vague, which is typical of reallife problems. In particular, what reasonable criterion can be used for defining the "best" route? How would you model this problem by a graph?

Problem sets should be submitted in PDF format. Formatting your problem set in LaTeX will make it easier for us to read; however, any method of generating the PDF is acceptable including scanning handwritten documents , as long as it is clearly legible. The problem sets include exercises that should be solved but not handed in. These questions are intended to help you master the course material and will be useful in solving the assigned problems. Material covered in exercises will be tested on exams. You should be as clear and precise as possible in your write-up of solutions. Understandability of your answer is as desirable as correctness, because communication of technical material is an important skill.

Levitin is also the author of Algorithmic Puzzles, publishing in Fall Design and Analysis of Algorithm is very important for designing algorithm to solve different types of problems in the branch of computer science and information technology. Topics include the following Worst and average case analysis. Recurrences and asymptotics. Efficient algorithms for sorting, searching, and selection. Data structures binary search trees, heaps, hash tables. Algorithm design techniques divide-and-conquer, dynamic programming, greedy algorithms, amortized analysis, randomization.

Solutions manuals are intended primarily for instructors, but it is a fact that instructors sometimes put copies in campus libraries or on their web pages for use by students. For instructors who prefer to have students work on problems without access to solutions, we have chosen not to include all the exercises from the text in this manual. The included exercises are listed in the table of contents. Roughly every other exercise is solved.

He stepped forward clutching his arm. Levitin is also the author of Algorithmic Puzzles, publishing in Fall They did some pretty amazing things the Swing Mikado was the most famous, like a saint in a procession.

Цель была достигнута. Все глобальное электронное сообщество было обведено вокруг пальца… или так только. ГЛАВА 5 Куда все подевались? - думала Сьюзан, идя по пустому помещению шифровалки.  - Ничего себе чрезвычайная ситуация.

На такой риск вы не пойдете. Сьюзан было запротестовала, но Стратмор не дал ей говорить. - Вы меня не знаете, молодой человек. Я рисковал всю свою жизнь. Хотите меня испытать.

Дверь подалась. Стратмор сменил положение. Вцепившись в левую створку, он тянул ее на себя, Сьюзан толкала правую створку в противоположном направлении. Через некоторое время им с огромным трудом удалось расширить щель до одного фута.

Хейл находился всего в метре от нее, когда она встала и преградила ему дорогу. Его массивная фигура буквально нависла над ней, запах одеколона ударил в ноздри. - Я сказала.  - Она смотрела ему прямо в .

- Сомневаюсь, что Танкадо пошел бы на риск, дав нам возможность угадать ключ к шифру-убийце. Сьюзан рассеянно кивнула, но тут же вспомнила, как Танкадо отдал им Северную Дакоту. Она вглядывалась в группы из четырех знаков, допуская, что Танкадо играет с ними в кошки-мышки. - Туннельный блок наполовину уничтожен! - крикнул техник.

Беккер почувствовал жжение в боку. Наверное, за ним тянется красный след на белых камнях. Он искал глазами открытую дверь или ворота - любой выход из этого бесконечного каньона, - но ничего не .

- Это составляло половину того, что у него было, и раз в десять больше настоящей стоимости кольца. Росио подняла брови. - Это очень большие деньги.

- Его столкнул вниз Стратмор. Я все это видел, потому что прятался в подсобке. Чатрукьян хотел вызвать службу безопасности, что разрушило бы все планы Стратмора. Ну и ловок, подумала Сьюзан.

Здесь есть браузер. Соши кивнула. - Лучше всего - Нетскейп. Сьюзан сжала ее руку.

ВР! - крикнула Соши, усаживаясь за компьютер в задней части комнаты. На стене ожила связанная с компьютером диаграмма.
