  2. All horses are the same color - Wikipedia

    en.wikipedia.org/wiki/All_horses_are_the_same_color

    All horses are the same color is a falsidical paradox that arises from a flawed use of mathematical induction to prove the statement All horses are the same color. [1] There is no actual contradiction, as these arguments have a crucial flaw that makes them incorrect.

  3. Pólya conjecture - Wikipedia

    en.wikipedia.org/wiki/Pólya_conjecture

    For this reason, it is more accurately called "Pólya's problem". The size of the smallest counterexample is often used to demonstrate the fact that a conjecture can be true for many cases and still fail to hold in general, [ 2 ] providing an illustration of the strong law of small numbers .

  4. How to Solve It - Wikipedia

    en.wikipedia.org/wiki/How_to_Solve_It

    Can you vary or change your problem to create a new problem (or set of problems) whose solution(s) will help you solve your original problem? Search: Auxiliary Problem: Can you find a subproblem or side problem whose solution will help you solve your problem? Subgoal: Here is a problem related to yours and solved before

  5. Inventor's paradox - Wikipedia

    en.wikipedia.org/wiki/Inventor's_paradox

    The inventor's paradox is a phenomenon that occurs in seeking a solution to a given problem. Instead of solving a specific type of problem, which would seem intuitively easier, it can be easier to solve a more general problem, which covers the specifics of the sought-after solution.

  6. Problems and Theorems in Analysis - Wikipedia

    Each volume the contains problems at the beginning and (brief) solutions at the end. As two authors have put it, "there is a general consensus among mathematicians that the two-volume Pólya-Szegő is the best written and most useful problem book in the history of mathematics." [1]: 59

  7. Pólya enumeration theorem - Wikipedia

    en.wikipedia.org/wiki/Pólya_enumeration_theorem

    The Polya enumeration theorem translates the recursive structure of rooted ternary trees into a functional equation for the generating function F(t) of rooted ternary trees by number of nodes. This is achieved by "coloring" the three children with rooted ternary trees, weighted by node number, so that the color generating function is given by f ...

  8. Pólya urn model - Wikipedia

    en.wikipedia.org/wiki/Pólya_urn_model

    Polya's Urn is a quintessential example of an exchangeable process. Suppose we have an urn containing γ {\displaystyle \gamma } white balls and α {\displaystyle \alpha } black balls. We proceed to draw balls at random from the urn.

  9. Negative binomial distribution - Wikipedia

    en.wikipedia.org/wiki/Negative_binomial_distribution

    The Pascal distribution (after Blaise Pascal) and Polya distribution (for George Pólya) are special cases of the negative binomial distribution. A convention among engineers, climatologists, and others is to use "negative binomial" or "Pascal" for the case of an integer-valued stopping-time parameter ( r {\displaystyle r} ) and use "Polya" for ...
