  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    In digital logic, a lookup table can be implemented with a multiplexer whose select lines are driven by the address signal and whose inputs are the values of the elements contained in the array. These values can either be hard-wired, as in an ASIC whose purpose is specific to a function, or provided by D latches which allow for configurable values.

  3. Stable marriage problem - Wikipedia

    en.wikipedia.org/wiki/Stable_marriage_problem

    The participants on one side of the matching (the hospitals) may have a numerical capacity, specifying the number of doctors they are willing to hire. The total number of participants on one side might not equal the total capacity to which they are to be matched on the other side. The resulting matching might not match all of the participants.

  4. Approximate string matching - Wikipedia

    en.wikipedia.org/wiki/Approximate_string_matching

    With the availability of large amounts of DNA data, matching of nucleotide sequences has become an important application. [1] Approximate matching is also used in spam filtering. [5] Record linkage is a common application where records from two disparate databases are matched. String matching cannot be used for most binary data, such as images ...

  5. Map matching - Wikipedia

    en.wikipedia.org/wiki/Map_matching

    Map matching is the problem of how to match recorded geographic coordinates to a logical model of the real world, typically using some form of Geographic Information System. The most common approach is to take recorded, serial location points (e.g. from GPS ) and relate them to edges in an existing street graph (network), usually in a sorted ...

  6. Perfectly matched layer - Wikipedia

    en.wikipedia.org/wiki/Perfectly_matched_layer

    PML is widely used and has become the absorbing boundary technique of choice in much of computational electromagnetism. [1] Although it works well in most cases, there are a few important cases in which it breaks down, suffering from unavoidable reflections or even exponential growth.

    Thus, upon the first iteration, page B would transfer half of its existing value (0.125) to page A and the other half (0.125) to page C. Page C would transfer all of its existing value (0.25) to the only page it links to, A. Since D had three outbound links, it would transfer one third of its existing value, or approximately 0.083, to A.

  8. Soundex - Wikipedia

    en.wikipedia.org/wiki/Soundex

    The Soundex code for a name consists of a letter followed by three numerical digits: the letter is the first letter of the name, and the digits encode the remaining consonants. Consonants at a similar place of articulation share the same digit so, for example, the labial consonants B, F, P, and V are each encoded as the number 1.

  9. Code-division multiple access - Wikipedia

    en.wikipedia.org/wiki/Code-division_multiple_access

    These vectors will be assigned to individual users and are called the code, chip code, or chipping code. In the interest of brevity, the rest of this example uses codes v with only two bits. Each user is associated with a different code, say v. A 1 bit is represented by transmitting a positive code v, and a 0 bit is represented by a negative ...
