Back in the euphoric early days of the Web, people liked to claim that much of the enormous potential in a company like Yahoo! was in the “eyeballs”—the simple fact that millions of people look at its pages every day. Further, by convincing people to register personal data with the site, a site like Yahoo! can show each user an extremely targeted advertisement whenever he or she visits the site, in a way that TV networks or magazines couldn’t hope to match. So if a user has told Yahoo! that he or she is a 20-year-old computer science major from Cornell University, the site can present a banner ad for apartments in Ithaca, New York; on the other hand, if he or she is a 50-year-old investment banker from Greenwich, Connecticut, the site can display a banner ad pitching Lincoln Town Cars instead.
But deciding on which ads to show to which people involves some serious computation behind the scenes. Suppose that the managers of a popular Web site have identified k distinct demographic groups G1, G2, . . . , Gk. (These groups can overlap; for example, G1 can be equal to all residents of New York State, and G2 can be equal to all people with a degree in computer science.) The site has contracts with m different advertisers, to show a certain number of copies of their ads to users of the site. Here’s what the contract with the ith advertiser looks like. 
. For a subset Xi ⊆ {G1, . . . , Gk} of the demographic groups, advertiser i wants its ads shown only to users who belong to at least one of the demographic groups in the set Xi.
. For a number ri, advertiser i wants its ads shown to at least ri users each minute. 
Now consider the problem of designing a good advertising policy— a way to show a single ad to each user of the site. Suppose at a given minute, there are n users visiting the site. Because we have registration information on each of these users, we know that user j (for j = 1, 2, . . . , n) belongs to a subset Uj ⊆ {G1, . . . , Gk} of the demographic groups. The problem is: Is there a way to show a single ad to each user so that the site’s contracts with each of the m advertisers is satisfied for this minute? (That is, for each i=1,2,…,m, can at least ri of the n users, each belonging to at least one demographic group in Xi, be shown an ad provided by advertiser i ?)
Give an efficient algorithm under the context of flow network to decide if this is possible, and if so, to actually choose an ad to show each user.

Let S_t denote price of GOOG stock in year t. Today the spot price is S_0=871.
S_1 has 40% chance of being 971 and 60% chance of being 771.
Find the range of risk-free rates r (risk-free interest rate is per annum with continuous compounding) such that you do NOT create an arbitrage opportunities when you initially take long OR short GOOG stock position at t=0 and then close out your position at t=1. (Note: this is only an arbitrage opportunity due to the model assumptions about S_1. In general, S_1 might reach $10^{100000} or $10^{ -100000} and so there is no bound on the range of r)

Need an argumentative essay on Alfred The Great. Needs to be 3 pages. Please no plagiarism.
King Alfred the Great is said to have quoted “I desired to live worthily as long as I lived, and to leave after my life, to the men who should come after me, the memory of me in good works.”
Alfred the Great is best remembered by many historians for his military feats. His victories against the Danes prove his capabilities as a great warrior.
He is credited with having built the first royal navy to combat the Danes. Alfred adopted the Danish strategy of building fortified bases. The Danes were defeated by the army of Alfred in May 878 in the Battle of Edington. When Alfred finally managed to defeat the Danes, instead of avenging the attacks, exhibited true statesmanship. He entertained the defeated Danish monarch and signed the Treaty of Wedmore, whereby he accepted the Danish occupation of East Anglia. Wessex was secured for Alfred and this resulted in lasting peace.
According to the peace treaty, Guthorn was baptized into the Christian faith and is troops from Wessex. Alfred Recognize the Danish control of East Anglia and a few parts of Mercia. In another treaty signed in 886 called the “Danelaw” the partition of England was formalized. After this, Alfred began fortifying his kingdom with forts to secure it from invasions. To augment his defenses, Alfred constructed a fleet of ships and thereby came to be famously called the “Father of the English Navy.” (Britannia)
The life of King Alfred is a life of “quiet virtue and unobtrusive success.” (Alfred the Great: The Truth Teller, Maker of England, 848-899 by Beatrice Adelaide Lees). He does not arouse strong feelings of passion that inspire poetry. Instead he is remembered as a friend of the poor, an ally of the clergy and a scholar king. Being a scholar himself, he is known to have translated many Latin books into the tongue of the Anglo Saxons. One of Alfred’s contemporary works that was left unfinished was a Latin account by Asser, a Welshman who was Alfred’s
