Class Work algorithms are used in every day life because they have a precise step by step way to get what you want. ADVANTAGES OF DES: 20. Expressing Algorithms to Computer To communicate algorithm to computer Need way to "represent" the algorithm Cannot use English Can use computer language machine language and programming languages (Java, Pascal, C) But, these are too tedious (&technical) Use Pseudo-Code instead... Pseudo-Code to express Algorithms Pseudo•Code Mixture of computer language and English Somewhere in between precise enough to describe what is meant without being too tediuos Examples: Let c be O; Sort the list of numbers in increasing order; Need to know both syntax — representation semantics — meaning, Characteristics of Algorithm Correctness Complexity --- time, space (memory), etc Ease of understanding Ease of coding Ease of maintainence. That's where computer algorithms come in. 3. All rights reserved. See our User Agreement and Privacy Policy.

Note the keywords: Finite set of steps; Unambiguous; Executable; Terminates; Algorithm Examples? You have not viewed any products yet. (Hint: How many integers are there?) Irrational Numbers Irrational numbers, which are similar to data sequences generated form chaotic system, are infinite and non-cyclic. The writer was able to write my paper by the deadline and it was very well written. Cipher feedback mode 4. Real Life Example: Cooking Framework: "Cooking or Recipe language' Algorithm: "Recipe for a Dish" (step by step instructions on how to cook a dish) Problem Decomposition Preparing Ingredients; Preparing Sauce; Real Life Example: Origami Framework: 'Origami or Paper-Folding language' Algorithm: "Sequence of Paper-Folding Instructions" (step by step instructions for each fold) Problem Decomposition Start with a Bird Base; . Section 18.3.6. Advanced Encryption Standard (AES). Coals of Algorithm Study To develop framework for instructing computer to perform tasks To introduce notion of algorithm as means of specifying how to solve a problem To introduce and appreciate approaches for defining and solving very complex tasks in terms of simpler tasks; Computer Science and Algorithms Computer Science can be considered... as study of algorithms including their formal properties Their hardware and software realisations Their applications to diverse areas, Algorithms: Real Life Examples Many Real-Life Examples Cooking: Recipe for preparing a dish Origami: The Art of Paper Folding Directions: How to go to Changi Airport Remember: Framework: How to give instructions; Alg: The actual step-by-step instructions; Abstraction: Decomposing / Simplifying.
