Industry:Computer science
A matrix that is only defined at (i,j) when i ≥ j.
Industry:Computer science
A maximal subset of edges of a connected graph such that the corresponding induced subgraph cannot be disconnected by deleting any vertex.
Industry:Computer science
A maximum-flow problem involving multiple commodities, in which each commodity has an associated demand and source-sink pairs.
Industry:Computer science
A means of searching protein databases to find those with the best alignment.
Industry:Computer science
A measure of a data structure whose change after an operation corresponds to the time cost of the operation.
Industry:Computer science
A measure of similarity between two strings. The Jaro measure is the weighted sum of percentage of matched characters from each file and transposed characters. Winkler increased this measure for matching initial characters, then rescaled it by a piecewise function, whose intervals and weights depend on the type of string (first name, last name, street, etc.).
Industry:Computer science
A measure of the maximum weight along paths in a weighted, directed graph.
Industry:Computer science
A measure of the resemblance of two (fixed) sets of geometric points P and Q, defined as H(P,Q)=max(max<sub>a∈ P</sub> min<sub>b∈ Q</sub> d(a,b), max<sub>a∈ Q</sub> min<sub>b∈ P</sub> d(a,b)) where d(·,·) is the distance metric, usually the Euclidean distance.
Industry:Computer science
A member of the sequence of numbers such that each number is the sum of the preceding two. The first seven numbers are 1, 1, 2, 3, 5, 8, and 13. F(n) ≈ round(Φ<sup>n</sup>/√ 5), where Φ=(1+√ 5)/2. Formal Definition: The n<sup>th</sup> Fibonacci number is <ul> <li>F(n) = F(n-1) + F(n-2), where F(1)=1 and F(2)=1, or <li>F(n) = (Φ<sup>n</sup> - φ<sup>n</sup>)/√ 5, where Φ=(1+√ 5)/2 and φ=(1-√ 5)/2. </ul>
