  2. First-fit-decreasing bin packing - Wikipedia

    en.wikipedia.org/wiki/First-fit-decreasing_bin...

    The FFD algorithm works as follows. Order the items from largest to smallest. Open a new empty bin, bin #1. For each item from largest to smallest, find the first bin into which the item fits, if any. If such a bin is found, put the new item in it. Otherwise, open a new empty bin put the new item in it.

  3. Queueing theory - Wikipedia

    en.wikipedia.org/wiki/Queueing_theory

    Customers with high priority are served first. [22] Priority queues can be of two types: non-preemptive (where a job in service cannot be interrupted) and preemptive (where a job in service can be interrupted by a higher-priority job). No work is lost in either model. [23] Shortest job first The next job to be served is the one with the ...

  4. First-fit bin packing - Wikipedia

    en.wikipedia.org/wiki/First-fit_bin_packing

    First-fit (FF) is an online algorithm for bin packing. Its input is a list of items of different sizes. Its input is a list of items of different sizes. Its output is a packing - a partition of the items into bins of fixed capacity, such that the sum of sizes of items in each bin is at most the capacity.

    So, for example, while a bank account may offer a primitive for increasing the balance, it would have no method called deposit. Such operations belong instead in the interaction part of DCI. [1] Data objects are instances of classes that might come from domain-driven design, and such classes might use subtyping relationships to organize domain ...

  6. Multilevel feedback queue - Wikipedia

    en.wikipedia.org/wiki/Multilevel_feedback_queue

    Processes in the base level queue can also be scheduled on a first come first served basis. [6] Optionally, if a process blocks for I/O, it is promoted one level, and placed at the end of the next-higher queue. This allows I/O bound processes to be favored by the scheduler and allows processes to escape the base-level queue.

  7. Jackson network - Wikipedia

    en.wikipedia.org/wiki/Jackson_network

    All service times are exponentially distributed and the service discipline at all queues is first-come, first-served, a customer completing service at queue i will either move to some new queue j with probability P i j {\displaystyle P_{ij}} or leave the system with probability 1 − ∑ j = 1 m P i j {\displaystyle 1-\sum _{j=1}^{m}P_{ij ...

    Numba is used from Python, as a tool (enabled by adding a decorator to relevant Python code), a JIT compiler that translates a subset of Python and NumPy code into fast machine code. Pythran compiles a subset of Python 3 to C++ . [164] RPython can be compiled to C, and is used to build the PyPy interpreter of Python.

  9. Gang scheduling - Wikipedia

    en.wikipedia.org/wiki/Gang_scheduling

    This algorithm is a modified version of the best fit algorithm. In the best fit algorithm, the PEs are allocated in a sequential order, but in this algorithm, the PEs can be inserted from both directions so as to reduce the overlap between different sets of PEs assigned to different jobs.
