  2. Big M method - Wikipedia

    en.wikipedia.org/wiki/Big_M_method

    For any greater-than constraints, introduce surplus s i and artificial variables a i (as shown below). Choose a large positive Value M and introduce a term in the objective of the form −M multiplying the artificial variables. For less-than or equal constraints, introduce slack variables s i so that all constraints are equalities.

  3. Knapsack problem - Wikipedia

    en.wikipedia.org/wiki/Knapsack_problem

    The algorithm takes (/) space, and efficient implementations of step 3 (for instance, sorting the subsets of B by weight, discarding subsets of B which weigh more than other subsets of B of greater or equal value, and using binary search to find the best match) result in a runtime of (/).

  4. Three-way comparison - Wikipedia

    en.wikipedia.org/wiki/Three-way_comparison

    In C++, the C++20 revision adds the spaceship operator <=>, which returns a value that encodes whether the 2 values are equal, less, greater, or unordered and can return different types depending on the strictness of the comparison. [3] The name's origin is due to it reminding Randal L. Schwartz of the spaceship in an HP BASIC Star Trek game. [4]

  5. dc (computer program) - Wikipedia

    en.wikipedia.org/wiki/Dc_(computer_program)

    dc (desk calculator) is a cross-platform reverse-Polish calculator which supports arbitrary-precision arithmetic. [1] It was written by Lorinda Cherry and Robert Morris at Bell Labs. [2] It is one of the oldest Unix utilities, preceding even the invention of the C programming language. Like other utilities of that vintage, it has a powerful set ...

  6. RPL (programming language) - Wikipedia

    en.wikipedia.org/wiki/RPL_(programming_language)

    RPL is a handheld calculator operating system and application programming language used on Hewlett-Packard's scientific graphing RPN (Reverse Polish Notation) calculators of the HP 28, 48, 49 and 50 series, but it is also usable on non-RPN calculators, such as the 38, 39 and 40 series.

  7. Digital comparator - Wikipedia

    en.wikipedia.org/wiki/Digital_comparator

    The binary variable (A=B) is 1 only if all pairs of digits of the two numbers are equal. Inequality In order to manually determine the greater of two binary numbers, we inspect the relative magnitudes of pairs of significant digits, starting from the most significant bit , gradually proceeding towards lower significant bits until an inequality ...

  8. Floor and ceiling functions - Wikipedia

    en.wikipedia.org/wiki/Floor_and_ceiling_functions

    In mathematics, the floor function is the function that takes as input a real number x, and gives as output the greatest integer less than or equal to x, denoted ⌊x⌋ or floor(x). Similarly, the ceiling function maps x to the least integer greater than or equal to x, denoted ⌈x⌉ or ceil(x). [1]

  9. Relational operator - Wikipedia

    en.wikipedia.org/wiki/Relational_operator

    two objects being equal but distinct, e.g., two $10 banknotes; two objects being equal but having different representation, e.g., a $1 bill and a $1 coin; two different references to the same object, e.g., two nicknames for the same person; In many modern programming languages, objects and data structures are accessed through references. In ...
