## CS 2251: Design and Analysis of Algorithms

An algorithm is a sequence of unambiguous instructions for solving a problem, i. Two nonnegative, not-both-zero integers m and n. Greatest common divisor of m and n.

What are Sequential Algorithms? The central assumption of the RAM model is that instructions are executed one after another, one operation at a time. Accordingly, algorithms designed to be executed on such machines are called Sequential algorithms. What are Parallel Algorithms? Cw2251 central assumption of the RAM model does not hold for some newer computers that can execute operations concurrently, i.

### ANNA UNIVERSITY: CS -DESIGN AND ANALYSIS OF ALGORITHMS UNIT I QUESTIONS

What is Exact algortihms Approximation algorithm? The principal decision to choose solving the problem exactly is called exact algorithm. The principal decision to choose solving the problem approximately is called Approximation algorithm.

What is Algorithm Design Technique? An algorithm design technique is a general approach to solving problems algorithmically that is applicable to a variety of problems from different areas of computing.

To prove that the algorithm yields a required result for every legitimate input in a finite amount of time. What is Efficiency of algorithm?

Efficiency of an algorithm can be precisely defined and investigated with mathematical rigor. There are two kinds of algorithm efficiency. What is generality of an cs225

It is a desirable characteristic of an algorithm. Generality of the problem the algorithm solves is sometimes easier to design an algorithm for a problem posed in more general terms. Optimality is about the complexity of the problem that algorithm solves. The sorting problem asks us to rearrange the items of aalysis given list in ascending order or descending order.

## CS2251 Design and analysis of algorithms BE CSE May June 2012 Question Paper

Desugn searching problem deals with finding a given value, called a search key, in a given set. In this running time will be the longest. In this running time will be the smallest.

What is called the basic operation of an algorithm? The most important algorith,s of the algorithm is the operation contributing the most to the total running time is called basic operation of an algorithm.

Then we can estimate the running time T n of a program implementing this algorithm on that computer by the formula. Define order of growth. To compare and rank such orders of growth we use three notations.

What is the use of Asymptotic Notations? The notations O, W and Q and are used to indicate and compare the asymptotic orders of growth of functions expressing algorithm efficiencies.
