    Often the graph that describes the structure of the computer network is the problem instance. This is illustrated in the following example. Different fields might take the following approaches: Centralized algorithms[ citation needed ] The graph G is encoded as a string, and the string is given as input to a computer.

    The computer program finds a coloring of the graph, encodes the coloring as a string, and outputs the result. Parallel algorithms Again, the graph G is encoded as a string. However, multiple computers can access the same string in parallel.

    Each computer might focus on one part of the graph and produce a coloring for that part. The main focus is on high-performance computation that exploits the processing power of multiple computers in parallel. Distributed algorithms The graph G is the structure of the computer network.

    There is one computer for each node of G and one communication link for each edge of G. Initially, each computer only knows about its immediate neighbors in the graph G; the computers must exchange messages with each other to discover more about the structure of G.

    Each computer must produce its own color as output. The main focus is on coordinating the operation of an arbitrary distributed system. For example, the Cole—Vishkin algorithm for graph coloring [39] was originally presented as a parallel algorithm, but the same technique can also be used directly as a distributed algorithm. Moreover, a parallel algorithm can be implemented either in a parallel system using shared memory or in a distributed system using message passing.

    Complexity measures[ edit ] In parallel algorithms, yet another resource in addition to time and space is the number of computers. Indeed, often there is a trade-off between the running time and the number of computers: the problem can be solved faster if there are more computers running in parallel see speedup.

    If a decision problem can be solved in polylogarithmic time by using a polynomial number of processors, then the problem is said to be in the class NC. Perhaps the simplest model of distributed computing is a synchronous system where all nodes operate in a lockstep fashion. In such systems, a central complexity measure is the number of synchronous communication rounds required to complete the task.

    Let D be the diameter of the network. On the one hand, any computable problem can be solved trivially in a synchronous distributed system in approximately 2D communication rounds: simply gather all information in one location D rounds , solve the problem, and inform each node about the solution D rounds.
