We present a hard instances generator for the Open Shop Scheduling Problems from .
The random instances generator takes the number of jobs n and the number of machines m as input and requires three parameters k, p and f .
A linear program is constituted of a linear objective function that models a profit to maximize or a cost to minimize, and a set of linear constraints that restrict decision variables. It has been the subject of very extensive research, and was given a major boost by Dantzig’s development of the Simplex method.
Mathematically, a linear program is formulated as:
It is pretty simple, all you need to do is create the base repo in your dropbox folder and push your code.
mkdir -p ~/myProject cd ~/myProject git init git add .
mkdir -p ~/Dropbox/Git cd ~/Dropbox/Git git init --bare myProject.git
cd ~/myProject git remote add origin ~/Dropbox/Git/myProject.git
echo >> "README.md" git add .git commit -m "first commit"
git push -u origin master
Here is a script that creates a new git project in
~/"new project" and initializes a git repo on your Dropbox folder (
gitdropbox myProject will do all of the above in one command.

In this article, we highlight 5 industries that cannot survive without Operations Research.
For an Electricity provider, the amount of energy injected into the electricity grid must be equal to the total energy consumed. All the time!
Each player in the electricity system must ensure a balance between the consumption of its customers and the production of its plants. To ensure this balance, the electricity producer realizes each day for the next day a forecast of the consumption of its customers and must build a production programs for each of its plants accordingly.
The development of these production programs is…
