Less flexible than lists because of their immutability, tuples are, however, of interest due to the fact that they occupy less memory and that their treatment is more effective. Since tuples are immutable, tuples are fixed. We can’t do anything to them in memory. Lists, however, have this method called append. In order for most of your appends to be fast, Python will actually create a larger array in memory just in case you append some values.

Tuples are similar to lists except that they are not mutable, i.e., the length and the content of the tuple cannot be changed at runtime. Syntactically, the list uses [ ] while tuples use ( ). Similar to lists, tuples may contain any data type including other tuples. Here are a few examples: >>> a = (1,2,3,4) >>> print(a) (1,2,3,4) >>> b = (3,) >>> c = ((1,2),(3,4))
Scripting in Python

A tuple is a collection of data of varying types which is not to be altered once established. The data within the tuple can be of any type such as integer, float, and strings. In fact, a tuple can contain other tuples, lists, dictionaries, sets, and any user-defined data type. A tuple is surrounded by parenthesis as shown in Code 3.7, which defines the variable as a tuple with an integer, a float, and a string.

Definition (3): A CLA is shown with the quintet so that: is a lattice, a d-tuple is an integer number, is a limited subset of which is called a neighbourhood vector so that ، shows a limited team of states. The state of the cell is shown as . In each cell of CLA, there is a team of LAs, which are shown by . shows the local rule of CLA in cell . So that the probable values, which are used for showing the reinforcement signal, are indicated by .
SCIP: global optimization of mixed-integer nonlinear programs in a branch-and-cut framework

A constraint integer program CIP is a tuple that encodes the task of solving where is the objective function vector, specifies the constraints, and specifies the set of variables that have to take integral values. Furthermore, a CIP has to fulfil the condition that for each fixed integer assignment the remaining feasible set must be polyhedral, i.e. there exist and such that where and .
