In computer science, the count-distinct problem [1] (also known in applied mathematics as the cardinality estimation problem) is the problem of finding the number of distinct elements in a data stream with repeated elements. This is a well-known problem with numerous applications.
In mathematics and logic, the term "uniqueness" refers to the property of being the one and only object satisfying a certain condition. [1] This sort of quantification is known as uniqueness quantification or unique existential quantification, and is often denoted with the symbols "∃!" [2] or "∃ =1". For example, the formal statement
At the most basic level, there is an essentially unique set of any given cardinality, whether one labels the elements {,,} or {,,}. In this case, the non-uniqueness of the isomorphism (e.g., match 1 to a {\displaystyle a} or 1 to c {\displaystyle c} ) is reflected in the symmetric group .

The degenerate distribution at x 0, where X is certain to take the value x 0. This does not look random, but it satisfies the definition of random variable. This is useful because it puts deterministic variables and random variables in the same formalism. The discrete uniform distribution, where all elements of a finite set are equally likely ...
MOSCOW (Reuters) -The Kremlin praised U.S. President-elect Donald Trump on Friday for criticising Ukrainian missile strikes deep into Russian territory but said discussions about deploying ...
The boy’s mother was knocked under the cab and the still-spinning wheel was on top of the kid’s leg, a tourist visiting from Oregon told ABC 7. The tourist and others nearby then dropped what ...
[1] In finite-element analysis , the essential or Dirichlet boundary condition is defined by weighted-integral form of a differential equation. [ 2 ] The dependent unknown u in the same form as the weight function w appearing in the boundary expression is termed a primary variable , and its specification constitutes the essential or Dirichlet ...
