As stated earlier, map and set only allow one instance of a key or element to be inserted into the container. If multiple instances of elements are required, use multimap or multiset. Both maps and sets support bidirectional iterators. For more information on iterators, see Iterators.
The use of frequency of repetition aids in the retrieval of relevant instances. The idea behind this phenomenon is that the more an instance is repeated within a category or list, the stronger the link between the two instances becomes. Individuals then use the strong association between the instances to determine the frequency of an instance.
A column selection is a text selection feature found in text editors which allows the user to select characters in a grid-like fashion, selecting characters in several lines at the same columns. This is usually initiated by pressing the alt key (instead of the shift key, which creates a continuous selection) to select text when dragging.
Algorithm selection (sometimes also called per-instance algorithm selection or offline algorithm selection) is a meta-algorithmic technique to choose an algorithm from a portfolio on an instance-by-instance basis. It is motivated by the observation that on many practical problems, different algorithms have different performance characteristics.
A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines.A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine.
For instance, consider "SELECT name from Student". In the case that there are multiple records with name "Sara" in the student table, all of them are shown. That means the result of an SQL query is a multiset; if the result were instead a set, the repetitive records in the result set would have been eliminated.
One more AFC playoff opening has already been claimed in Week 16. By the end of Sunday, the conference's field could be fully locked in. The Baltimore Ravens sealed their spot on Saturday with a ...
Polyinstantiation in computer science is the concept of type (class, database row or otherwise) being instantiated into multiple independent instances (objects, copies). It may also indicate, such as in the case of database polyinstantiation, that two different instances have the same name (identifier, primary key).
