    The divide-and-conquer paradigm is often used to find an optimal solution of a problem. Its basic idea is to decompose a given problem into two or more similar, but simpler, subproblems, to solve them in turn, and to compose their solutions to solve the given problem. Problems of sufficient simplicity are solved directly. For example, to sort a giv...

    Early examples of these algorithms are primarily decrease and conquer – the original problem is successively broken down into singlesubproblems, and indeed can be solved iteratively. Binary search, a decrease-and-conquer algorithm where the subproblems are of roughly half the original size, has a long history. While a clear description of the algor...

    Solving difficult problems

    Divide and conquer is a powerful tool for solving conceptually difficult problems: all it requires is a way of breaking the problem into sub-problems, of solving the trivial cases, and of combining sub-problems to the original problem. Similarly, decrease and conquer only requires reducing the problem to a single smaller problem, such as the classic Tower of Hanoi puzzle, which reduces moving a tower of height n {\displaystyle n} to move a tower of height n − 1 {\displaystyle n-1} .

    Algorithm efficiency

    The divide-and-conquer paradigm often helps in the discovery of efficient algorithms. It was the key, for example, to Karatsuba's fast multiplication method, the quicksort and mergesort algorithms, the Strassen algorithm for matrix multiplication, and fast Fourier transforms. In all these examples, the D&C approach led to an improvement in the asymptotic cost of the solution. For example, if (a) the base cases have constant-bounded size, the work of splitting the problem and combining the par...

    Parallelism

    Divide-and-conquer algorithms are naturally adapted for execution in multi-processor machines, especially shared-memory systems where the communication of data between processorsdoes not need to be planned in advance because distinct sub-problems can be executed on different processors.

    Recursion

    Divide-and-conquer algorithms are naturally implemented as recursive procedures. In that case, the partial sub-problems leading to the one currently being solved are automatically stored in the procedure call stack. A recursive function is a function that calls itself within its definition.

    Explicit stack

    Divide-and-conquer algorithms can also be implemented by a non-recursive program that stores the partial sub-problems in some explicit data structure, such as a stack, queue, or priority queue. This approach allows more freedom in the choice of the sub-problem that is to be solved next, a feature that is important in some applications — e.g. in breadth-first recursion and the branch-and-boundmethod for function optimization. This approach is also the standard solution in programming languages...

    Stack size

    In recursive implementations of D&C algorithms, one must make sure that there is sufficient memory allocated for the recursion stack, otherwise, the execution may fail because of stack overflow. D&C algorithms that are time-efficient often have relatively small recursion depth. For example, the quicksort algorithm can be implemented so that it never requires more than log 2 ⁡ n {\displaystyle \log _{2}n} nested recursive calls to sort n {\displaystyle n} items. Stack overflow may be difficult...

  3. En informatique, diviser pour régner (du latin « Divide ut imperes », divide and conquer en anglais) est une technique algorithmique consistant à : Diviser : découper un problème initial en sous-problèmes ; Régner : résoudre les sous-problèmes (récursivement ou directement s'ils sont assez petits) ;

  4. Conquer Divide is an American rock band whose members are from the United States, the United Kingdom, and Canada, with one former member coming from Serbia.

  5. Divide and rule policy (Latin: divide et impera), or divide and conquer, in politics and sociology is gaining and maintaining power divisively. This includes the exploitation of existing divisions within a political group by its political opponents, and also the deliberate creation or strengthening of such divisions.
