Ruby is a dynamic‚ open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby is a language of careful balance. Ruby is a pure object-oriented programming language. Ruby is simple in appearance‚ but is very complex inside‚ just like our human body. In Ruby‚ everything is an object. Every bit of information and code can be given their own properties and actions. Ruby has features that are similar to those

facilitated students to solve small programming problems assignments. This technique; identifies the steps involved in each process to be performed and the inputs to and outputs from each step. However‚ this technique lacks the proper procedures to identify the root or roots of the problem. Therefore‚ this technique leaves the student without the understanding of what the problem is and what is really causing it [3]. In the real world computer or programming analysts are confronted with more complicated

Exercise 4.32 [Assessment 2(16): You must have this exercise signed off by your class supervisor] On paper‚ write a method called sum with a while loop that adds up all numbers between two numbers a and b‚ inclusive‚ and returns the sum as its result. The values for a and b can be passed to the sum method as parameters. For instance: sum(1‚ 5) would return the value 15 (i.e.‚ 1 + 2 + 3 + 4 + 5). What happens if the value of the second parameter is less than the value of the first? public

Primal-Dual Approximation Algorithms We just saw how the primal-dual schema permits sometimes designing efficient combinatorial algorithms for solving certain problems. We will now see an example of how a related technique can sometimes be used to design efficient approximation algorithms The major tool that we will use will be the RELAXED Complementary Slackness conditions The problem we examine will again be weighted set-cover. 1 Recall that given canonical primal n minimize
