  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    LUTs differ from hash tables in a way that, to retrieve a value with key , a hash table would store the value in the slot () where is a hash function i.e. is used to compute the slot, while in the case of LUT, the value is stored in slot , thus directly addressable.

  3. Input Field Separators - Wikipedia

    en.wikipedia.org/wiki/Input_Field_Separators

    If IFS has a value other than the default, then sequences of the whitespace characters space and tab are ignored at the beginning and end of the word, as long as the whitespace character is in the value of IFS (an IFS whitespace character). Any character in IFS that is not IFS whitespace, along with any adjacent IFS whitespace characters ...

  4. IFS AB - Wikipedia

    en.wikipedia.org/wiki/IFS_AB

    In 1996, IFS was listed in the Swedish stock exchange and the product was made into a component based one. This was followed with the launch of its web client and its establishment of an RnD center in Colombo. In 2001, IFS introduced Java-based mobile clients and Internet portals. In 2004, NEC acquired a 7.7% of IFS share capital. By 2005, IFS ...

  5. RE/flex - Wikipedia

    en.wikipedia.org/wiki/Re/flex

    RE/flex differs from Lex and Flex in that the generated tables contain a list of opcode words executed by a virtual machine to perform pattern matching. In addition, a DFA implemented in code instead of opcode tables is generated with the --fast option. For example, the following direct-coded DFA for pattern \w+ is generated with option --fast:

  6. Iterated function system - Wikipedia

    en.wikipedia.org/wiki/Iterated_function_system

    Construction of an IFS by the chaos game (animated) IFS being made with two functions. Hutchinson showed that, for the metric space R n {\displaystyle \mathbb {R} ^{n}} , or more generally, for a complete metric space X {\displaystyle X} , such a system of functions has a unique nonempty compact (closed and bounded) fixed set S .

  7. Conditional (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Conditional_(computer...

    If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.

  8. Table (database) - Wikipedia

    en.wikipedia.org/wiki/Table_(database)

    In a database, a table is a collection of related data organized in table format; consisting of columns and rows.. In relational databases, and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect.

  9. Four-valued logic - Wikipedia

    en.wikipedia.org/wiki/Four-valued_logic

    The four values are 1, 0, Z and X. 1 and 0 stand for Boolean true and false, Z stands for high impedance or open circuit and X stands for don't care (e.g., the value has no effect). This logic is itself a subset of the 9-valued logic standard called IEEE 1164 and implemented in Very High Speed Integrated Circuit Hardware Description Language ...
