Which is the best-known publicly accessible wiki? How does it function?
What will be an ideal response?
The online encyclopedia called Wikipedia is the best-known publicly accessible wiki. With millions of articles contributed by volunteers around the world, the nonprofit Wikipedia is the most popular general-purpose reference work on the net. People can update any of the existing articles with current information. Critics point to problems with accuracy and bias, exacerbated by the site's open structure that allows anyone promoting an agenda to edit articles. Corporations and government agencies are known to quietly edit entries about themselves to put out the best spin wherever possible. Occasionally, the site blocks people from changing an article, especially when it deals with controversial current events.

What is an appropriate objective function for this scenario?
The department chair reviewed last year's schedule, the degree requirements for the ever popular Operations and Supply Chain major, and the emails that had drifted into her mailbox over the last week. Naturally, every professor in the department had his own pet course and wanted to maintain control of it while avoiding 8 a.m. classes at all costs. In an effort to placate the senior faculty members of the department, the chair sent an email asking them to supply the prep time for each of the classes they were qualified to teach, promising to assign them the least taxing schedule possible. Each of her department members had to teach at least two courses, but no more than three. The elective courses, Project Management, Quality Management, Control and Planning, Logistics, and Management Science each had to be offered once and the department needed to offer at least six sections of the Introduction to Operations class. The prep times each professor estimated for each course appear in the table below.
