Adding an example

This page explains how to add your own data/simulation code/... to the toolbox in order to model it.

Project directories

The SUMO Toolbox comes with a large number of example problems and datasets which you can use for testing, benchmarking, or simply to get a feel of what is possible. These problems cover a very large range of domains, from Biology to Geography and Electronics. If you simply want to play around and try different examples please refer to Running#Running_different_examples.

All the files related to one problem are placed together in a directory. We call this the project directory for that problem. Many examples of project directories can be found in the examples/ subdirectory of your SUMO-Toolbox installation. If you open one of those directories you will see they contain the following things:

  1. A simulator xml file with the same name as the project directory. This file is mandatory (though there are some small exceptions)
  2. One or more executables: matlab script, C++ file, binary, ... (optional)
  3. One or more data files (optional)
  4. Alternative simulator xml files (optional)
  5. Other files, e.g., a documenting pdf (optional)

Open up a couple of the example project directories and have a look inside so you are sure whats going on.

Modeling your own problem

If you want to model your own problem, this means you have to create a new project directory and give it a name. For ease of use we suggest to create it in the examples/ subdirectory. For example, if your problem is called Foobar create the directory examples/Foobar. Inside this directory you must place: a file called Foobar.xml, this is the simulator configuration file. See the simulator configuration page for information how to write such a file.

Once you have this file you simply place place any datasets, Matlab scripts, ... into your project directory. If you specified the correct path in your simulator configuration file then SUMO will find them. Paths can be absolute or relative to the project directory. If no file extension is present, '.txt' is assumed.

Having written your simulator XML file and provided the datasets/executables you now just need to change default.xml so it uses your problem (<Simulator> tag). For information on this see Running#Running different examples.
