The goal is to implement a dynamic programming algorithm Linux packages to include on installation media, using the knapsack This test program will reduce the problem of selecting which Debian

measures the elapsed time of the code corresponding to the algorithm Description: This is the test harness program which runs the code and Code for “ Project2.h” can be found here.Code for the Timer class ( Timer.h) can be found here.Note: This program uses two external header files (Timer.h and Project2.h).

In other words, to create a problem instance with n = 100, only use the first 100 packages listed in the file as input. A solution is the best sequence of packages, displaying the name of the package, the votes, and the size of each package, as well as the total votes and total size of the entire solution.Ī knapsack problem instances is created of varying input sizes “n” by using the first “n” entries in the file knapsack_packages.txt. Print the first 20 packages from the solution. The output of this algorithm should be the best combination sequence of packages.Ĥ. Input size 'n' and weight 'W' as variables.ģ. Load the 'knapsack_packages.txt' file into memory.Ģ. The test program will perform the following steps:ġ. The packages are arranged within the file in sorted order, from the largest number of votes to the smallest.Ī test harness program is created which executes the above function and measures the elapsed time of the code corresponding to the algorithm in question. The following file ( knapsack_packages.txt) contains the name, size, and votes for approximately 36,000 binary Debian packages that are currently available on the amd64 platform, and have popcon information. In terms of the knapsack problem, the Debian package votes correspond to knapsack values, and our Debian package sizes correspond to knapsack weights. Output: The set of packages with total size ≤ W, such that the total number of package votes is maximized.

Input: A list of Debian packages, each with a size (in kilobytes) and number of votes, both of which are integers and an integer W representing the capacity of the install media (in kilobytes). This program solves the following problem: W) time, returning the optimal set of items/packages contained in the input file, which is fast enough to produce solutions to inputs of realistic size.The goal of this program is to implement a dynamic programming algorithm which runs in O(n 2 The Exhaustive Search algorithm ran in O(2 n) time and was very slow. So, thanks to popcon, we can get a vote tally for each package. Users may elect to participate, in which case the list of their installed packages is transmitted back to Debian. The Popularity Contest tries to measure the popularity of each Debian package. It is impractical to include every package on those media, so the Debian project needs to select a small subset of important packages to include.Īnother part of Debian is the Popularity Contest, or popcon:

#KNAPSACK DYNAMIC PROGRAMMING DOWNLOAD#

If a user wants to install a package that is missing from their installation media they need to download it over the internet, so it is beneficial to include as many packages as possible. However it poses a problem for creating installation media – the floppy disks, CDs, DVDs, or flash drive images that administrators use to install the operating system. This wide selection of packages is mostly a good thing. There are currently over 29,000 Debian source code packages available.

#KNAPSACK DYNAMIC PROGRAMMING SOFTWARE#

Nearly every piece of noteworthy open source software has a corresponding package.

There are packages not only for the software that comprises the operating system, but also end-user applications. Each package corresponds to a software component, such as the GCC compiler or Firefox web browser. Debian software is organized into packages. Ubuntu Linux, arguably the most popular Linux distribution, is based on Debian. Debian is a well-established GNU/Linux distribution.
