Complete Vs. Perfect Information
Complete and perfect information are importantly different. In a game of complete information, the structure of the game and the payoff functions of the players are commonly known but players may not see all of the moves made by other players (for instance, the initial placement of ships in Battleship); there may also be a chance element (as in most card games). Games of incomplete information arise most frequently in social science rather than as games in the narrow sense. For instance, Harsanyi was motivated by consideration of arms control negotiations, where the players may be uncertain both of the capabilities of their opponents and of their desires and beliefs. Games of incomplete information can be converted into games of complete but imperfect information under the "common prior assumption." This assumption is commonly made for pragmatic reasons, but its justification remains controversial.

Famous quotes containing the words complete, perfect and/or information:
“What I expect from my male friends is that they are polite and clean. What I expect from my female friends is unconditional love, the ability to finish my sentences for me when I am sobbing, a complete and total willingness to pour their hearts out to me, and the ability to tell me why the meat thermometer isn’t supposed to touch the bone.”
—Anna Quindlen (20th century)
“I call the years when our children are between six and twelve the “golden years,” not because everything’s perfect . . . but because the kids are capable and independent. . . . They’re becoming fascinating human beings who continually astound us and make us laugh. And they build our self-esteem. They still adore us for the most part, not yet having reached that age of thinking everything we do is dumb, old-fashioned and irrelevant.”
—Vicki Lansky (20th century)
“On the breasts of a barmaid in Sale
Were tattooed the prices of ale;
And on her behind
For the sake of the blind
Was the same information in Braille.”
