INFORMATION TECHNOLOGY ASSIGNMENT ON ALGORITHM Done by Densil Hamilton INTRODUCTION This Assignment was done to show the methods of algorithm. It outlines the meaning of algorithm and steps to be carried out to complete a give problem. Examples were also shown for the methods of representing algorithm. What is an Algorithm? An algorithm consists of a set of explicit and unambiguous finite steps which‚ when carried out for a given set of initial conditions‚ produce the corresponding

types of algorithms and this is the reasons behind the success of this applications. Algorithms is a formula or set of steps for solving a particular problem. A set of rules must be unambiguous and have a clear stopping point. Algorithm can be expressed in any language‚ from natural languages like English or French to programming languages like FORTRAN. Most programs‚ with the exception of some artificial intelligence applications‚ consist of algorithms. Inventing elegant algorithms that are simple

Lab Report for Computer Assignment #2 GPS Algorithm Introduction In order to guide each object correctly on the earth‚ the GPS satellites need to locate them very accurately. The goal of the assignment is to use some optimization methods to locate an object with given pseudo-range data. The signals which are sent from satellites to the target are not accurate because the systematic errors caused by inaccurate receiver clock and some other random noise. The un-accurate range is known as pseudo-range

APRIORI Algorithm Professor Anita Wasilewska Lecture Notes The Apriori Algorithm: Basics The Apriori Algorithm is an influential algorithm for mining frequent itemsets for boolean association rules. Key Concepts : • Frequent Itemsets: The sets of item which has minimum support (denoted by Li for ith-Itemset). • Apriori Property: Any subset of frequent itemset must be frequent. • Join Operation: To find Lk ‚ a set of candidate k-itemsets is generated by joining Lk-1 with itself. The Apriori

Algorithm The term algorithm is often used to refer to the logic of a program It is a step-by step description of how to arrive at the solution of the given problem. It may be formally defined as a sequence of instructions‚ designed in a manner that‚ if the instructions are executed in the specified sequence‚ the desired results will be obtained. In order to qualify as an algorithm‚ a sequence of instructions must possess the following characteristics: Sample Algorithms 50 Students in a class

The RSA Algorithm Evgeny Milanov 3 June 2009 In 1978‚ Ron Rivest‚ Adi Shamir‚ and Leonard Adleman introduced a cryptographic algorithm‚ which was essentially to replace the less secure National Bureau of Standards (NBS) algorithm. Most importantly‚ RSA implements a public-key cryptosystem‚ as well as digital signatures. RSA is motivated by the published works of Diffie and Hellman from several years before‚ who described the idea of such an algorithm‚ but never truly developed it. Introduced at the

2. The following algorithm is to be applied to the positive integers from 1 to 12. Step 1: Cross out every even number. Step 2: Change the state of every multiple of 3 (including 3) – i.e. for every multiple of 3‚ if it is crossed out then remove the crossing out‚ and if it is not crossed out then cross it out. Step 3: Change the state of every multiple of 4 (including 4). Step 4: Change the state of every multiple of 5 (including 5). … … Step 11: Change the state
