  2. Closest string - Wikipedia

    en.wikipedia.org/wiki/Closest_string

    More formally, given n strings s 1, s 2, ..., s n of length m, the closest string problem seeks a new string s of length m such that d(s,s i) ≤ k for all i, where d is the Hamming distance, and where k is as small as possible. [2]

    The empty string is the unique string over Σ of length 0, and is denoted ε or λ. [25] [26] The set of all strings over Σ of length n is denoted Σ n. For example, if Σ = {0, 1}, then Σ 2 = {00, 01, 10, 11}. We have Σ 0 = {ε} for every alphabet Σ. The set of all strings over Σ of any length is the Kleene closure of Σ and is denoted Σ *.

  5. Free variables and bound variables - Wikipedia

    en.wikipedia.org/wiki/Free_variables_and_bound...

    In the lambda calculus, x is a bound variable in the term M = λx. T and a free variable in the term T. We say x is bound in M and free in T. If T contains a subterm λx. U then x is rebound in this term. This nested, inner binding of x is said to "shadow" the outer binding. Occurrences of x in U are free occurrences of the new x. [3]

  6. Escape analysis - Wikipedia

    en.wikipedia.org/wiki/Escape_analysis

    The popularity of the Java programming language has made escape analysis a target of interest. Java's combination of heap-only object allocation, built-in threading, the Sun HotSpot dynamic compiler, and OpenJ9 's just-in-time compiler (JIT) creates a candidate platform for escape analysis related optimizations (see Escape analysis in Java ).

    Java provides default interface methods since version 8. [4]: 104 Project Lombok [13] supports delegation using the @Delegate annotation on the field, instead of copying and maintaining the names and types of all the methods from the delegated field. [14] Julia macros can be used to generate forwarding methods.

  9. Factory method pattern - Wikipedia

    en.wikipedia.org/wiki/Factory_method_pattern

    [4] In the above UML class diagram , the Creator class that requires a Product object does not instantiate the Product1 class directly. Instead, the Creator refers to a separate factoryMethod() to create a product object, which makes the Creator independent of the exact concrete class that is instantiated.
