    Hello,


    About my linear programming modeling examples in Object Pascal..

    I have just updated my Linear programming modeling examples in Object
    Pascal, and i have just included the last stable version of 64bit
    Symphony MILP solver inside the zip file, so just pass it the MPS output
    file from the object pascal example.

    You can download it from:

    And about optimization..

    Advances in integer optimization from 1988 to 2017:

    – Improved algorithms and methods: 147,650 times faster

    – Improved computing power: 17,120 times faster

    – Overall improvement: 2,527,768,000 times faster

    In practice, this means that solving a typical MILP problem would have
    taken 80 years back in 1988, whereas today it only takes one second.
    However, while MILP problem solving is nowadays standard technology,
    MINLP problems still pose a challenge.This is motivating and inspiring researchers in the field.

    Optimization is a special area within Mathematics and Engineering. The
    idea of optimization is to find the best possible – or a sufficiently
    good – solution to a problem given in the form of a mathematical
    description of a system or process.

    And about optimization, i have just included the 64 bit SYMPHONY solver
    for mixed-integer linear programs (MILPs), with a batch file that
    executes the MPS file, inside the zip file that you can download from here:

    https://sites.google.com/site/scalable68/linear-programming-modeling-examples-in-object-pascal

    And you can read this interesting webpage and you will notice on the
    benchmark that SYMPHONY solver is good:

    the Shortest-Route problem in object pascal to understand more:
