3 Greedy Algorithm
Greedy technique is an algorithm design policy, built on configurations such as different choices, values to find objective .Greedy algorithms produce good solutions on mathematical problems. The main aim is to find some configurations that are either maximized or minimized. Greedy Algorithms provide a solution for optimization problems that has certain sequence of steps, with a set of choices for each step. Another solution for Greedy algorithm is dynamic programming . It is also used to determine the best choices. But greedy algorithm always makes the choice that is best at the moment to provide the optimal solution for the problem. A greedy algorithm for an optimization always provides the current sub solution. Basically greedy algorithm always gives an optimal solution to the MST (Minimum Spanning tree)problem. Some Examples that are solved by greedy algorithm are Dijkstra’s shortest path algorithm and Prim/Kruskal’s algorithms.
Greedy algorithm technique relies on following elements:
• configurations: It consists of different choices, values to apply on data.
• objective : some configurations to be either maximized or minimized to get the predefined objective.
Greedy algorithms are applicable to optimization problems

On the other hand it shows that data mining can become both a source of making discrimination and discovering discrimination items present in the dataset. Discrimination of data is categorized in two types as direct discrimination and indirect discrimination. Direct discrimination consists of data mining rules that inherently mention underprivileged groups based on sensitive discriminatory parameters present in that data set. Indirect discrimination consists of data mining rules that will not explicitly mentions the discriminatory
Social class is another important type in which discrimination is based upon. Our social class is apparent from the place where we live. The higher the class, the better the place is kept and maintained. This inequality has also infiltrated health and social care. For example members of the department of health publication claim that the poor are more likely to get cancer than the rich, and their chances of survival are lower too. However at the
Discrimination is when an individual or group of people are treated more or less favorably than others.
What is discrimination you ask well it is the treatment or consideration of, or making
Discrimination: Discrimination in itself is purposeful exclusion of an individual or group based on specific characteristics. It could be direct, indirect or combined. People that are already vulnerable in most cases find it have to bounce back from it.
The process of establishing if an action/policy is discriminatory can be very challenging. However, a number of theories seek to differentiate actions that constitute discrimination and those that do not. Disparate treatment Theory is amongst the most commonly used theories that have been used to ascertain whether an act or policy amounts to discrimination or not. The theory argues that one is subject to discrimination if they are treated less favorably than others are in similar situations (Bent, 2011).
(TCO B) For a project, the objective is usually defined in terms of which three
Starting off with the first discriminatory classification, The Suspect Classification, helps represents a large portion of our population. In this classification the people getting discriminated are based on race, national origin, religion, and alienage. With the race discriminatory factor, it is when “someone is treated unfavorably because he/she is of a certain race or because of personal
Discrimination can be defined as the differential treatment or judgment against a group such as class status, nationality, religion, etc. There are several reasons why people may think people of color are "bad" and get discriminated against more then those who are White or Asian. Maybe it is because for every three colored men at least one will serve a prison sentence. Many studies target those with colored skin because they were the first kind of people to go to a jail. Continuing, there are several kind different forms of discrimination (institutionalized, systematic, contextual, and individual acts of discrimination). First, the institutionalized information is based on the criminal record or behavior. Second, the systematic is discrimination in the criminal justice system. Third, the contextual information is based on particular crimes. Lastly, individual acts of discrimination is based the acts of the individual. Discrimination is revealed to the individual in many different aspects and treatment received based on group affiliation such as nationality, classes status, and much more. For example, in law enforcement they see a woman down a street known where prostitutes are. What the police officer does not know if the woman is coming from a bar, and she is walking home. The police officer pulls over, stops her, and arrests
Management wanted to use this information to objectively determine: 1) the optimal reorder point, and once this was fixed, 2) to compute the optimal quantity of cases to order each time.
Discrimination is the unjust or prejudicial treatment of different categories of people or things. Discrimination in Of Mice And Men is age, race, gender, and disability. The Sneetches had discrimination both when they did and did not have stars on their bellies. Even with all discrimination issues throughout history we have all not learned to get along. In conclusion discrimination happens to all of
Principles that underlines the process of selection and the choice of techniques are two key principles;
With the increased and widespread use of technologies, interest in data mining has increased rapidly. Companies are now utilized data mining techniques to exam their database looking for trends, relationships, and outcomes to enhance their overall operations and discover new patterns that may allow them to better serve their customers. Data mining provides numerous benefits to businesses, government, society as well as individual persons. However, like many technologies, there are negative things that caused by data mining such as invasion of privacy right. This paper tries to explore the advantages as well as the disadvantages of data mining. In addition, the ethical and global issues regarding the use of data mining
The objective function, decision variables and constraints are fed into solver to arrive at the optimal solution as shown in the below screenshot
Exact optimisation method is the optimisation method that can guarantee to find all optimal solutions. In principle, the optimality of generated solution can be proofed mathematically. Therefore, exact optimisation is also termed as mathematical optimisation. However, exact optimisation approach is impractical usually. The effort of solving an optimisation problem by exact optimisation grows polynomially with the problem size. For example, to solve a problem by brute force approach, the execution time increases exponentially respect to the dimensions of the problem.
