Convex set quiz: 3 questions
Three questions on the Convex set card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
The ______ of a convex set in the plane is always a convex curve.
Answer
boundary. The boundary of a convex set in the plane is always a convex curve. From the Convex set article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Algebraic variety. Algebraic variety 74 · Fuel 71 · Convex set 68 · Adipocyte 65 ATK in WikiCards.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- For example, a solid cube is a convex set, but anything that is hollow or has an indent, such as a crescent shape, is not convex.
- The boundary of a convex set in the plane is always a convex curve.
- The intersection of all the convex sets that contain a given subset A of Euclidean space is called the convex hull of A. It is the smallest convex set containing A. A convex function is a real-valued function defined on an interval with the property that its epigraph is a convex set.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Convex set article was read about 55,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 59: each hit it takes is cut by 24 %.
How to get Convex set
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
