In this tutorial I will describe how to install Microsoft Visual Studio Express 2012.
Start by downloading MS Visual Studio Express 2012 for free from MS Visual Studio Express 2012. Install the downloaded file as shown in the picture below.
Often when writing a model, the most straightforward way of writing a constraint is by multiplying two variables. Then, in order to solve the model we need to linearize it. There comes the problem, as I always have problems reminding how to linearize a product of variables.
Suppose your model has the product , where , and are binary. There is an easy way of linearizing that equation. Add the three inequalities below
When preparing a new LaTeX manuscript, we often do not know to which journal it will be submitted. Then we need a nice style to present the content. Likewise to reports and the likes.
LaTeX offers its amsarticle document class, which is generally good. I mean generally because it can (and should) be improved to meet one’s needs.
My needs are satisfied with the following template, which modifies the margins and adds my usually needed packages.
Concorde TSP is one of the best solvers for the Traveling Salesman Problem. Its current version was released in 2003, but it is still considered to be the state of the art in its field.
CPLEX is a general purpose solver. It is also considered to be one of the best in its class.
In order to obtain exact solutions with Concorde, one needs to link it to a solver. However, Concorde’s documentation falls short, since in 2003 CPLEX’s version was 8.0, and it is currently under version 12.5 (as of november 2012).
In order to link and compile Concorde with CPLEX, you will need to make the following modifications:
