    Select a single character from one of the alternative character sets. SS2 selects the G2 character set, and SS3 selects the G3 character set. [13] In a 7-bit environment, this is followed by one or more GL bytes (0x20–0x7F) specifying a character from that set. [12]: 9.4 In an 8-bit environment, these may instead be GR bytes (0xA0–0xFF).

  3. Named parameter - Wikipedia

    en.wikipedia.org/wiki/Named_parameter

    Without named parameters, optional parameters can only appear at the end of the parameter list, since there is no other way to determine which values have been omitted. In languages that support named optional parameters, however, programs may supply any subset of the available parameters, and the names are used to determine which values have ...

    In computer science, a semaphore is a variable or abstract data type used to control access to a common resource by multiple threads and avoid critical section problems in a concurrent system such as a multitasking operating system. Semaphores are a type of synchronization primitive. A trivial semaphore is a plain variable that is changed (for ...

  5. String operations - Wikipedia

    en.wikipedia.org/wiki/String_operations

    The right quotient of a character a from a string s is the truncation of the character a in the string s, from the right hand side. It is denoted as /. If the string does not have a on the right hand side, the result is the empty string. Thus:

  6. C string handling - Wikipedia

    en.wikipedia.org/wiki/C_string_handling

    The length of a string is the number of code units before the zero code unit. [1] The memory occupied by a string is always one more code unit than the length, as space is needed to store the zero terminator. Generally, the term string means a string where the code unit is of type char, which is exactly 8 bits on all modern machines.

    A hyperparameter is a parameter whose value is used to control the learning process, which must be configured before the process starts. [ 2 ] [ 3 ] Hyperparameter optimization determines the set of hyperparameters that yields an optimal model which minimizes a predefined loss function on a given data set . [ 4 ]
