Gusek

Gusek is an open-source LP/MIP IDE for GLPK that comes packed with a custom version of the SciTE text editor linked to the GLPK standalone solver. The package runs on 32-bit Windows systems.

Portable running mode 

You can take advantage of the fact that the program comes packed in a portable package and store it on USB flash drives or other portable devices. You can run it without having to follow the steps of an installation process.

User interface

The GUI provides a well-structured suite of features. This does not necessarily mean that you can decode its features very quickly. There’s support for an advanced set of configuration settings, so you need to dedicate some of your time to get an idea how it works.
The multi-tabbed environment helps you keep different projects opened at the same time and switch between them. Plus, you can integrate the utility within Windows Explorer’s contextual menu and make file associations to GMPL model extensions.

Importing/exporting options

You are given the freedom to add data from various file formats, such as MOD, DAT, OUT, MPS, LP, LUA, and JAVA. You are allowed to print or export the information to RTF, HTML, PDF, XML, and LaTeX files.

GLPK model development tools

Aside from the features included in the SciTE editor, the application gives you the possibility to work with several resources specific for GLPK models development.
Gusek allows you to verify model/data syntax, solve the current model, and build problems in GLPK LP/MIP, CPLEX LP or MPS format.
What’s more, you can enable or disable the use of external data files, set the default DAT file, add the actual data file as ‘extra data file,’ clear the register of ‘extra data files,’ and turn on or off several options, like output file creation, LP sensitivity analysis, and improved MILP.
The program offers you the option to develop models using the default GLPK modelling language and create them using two different modes: single or multiple files. The single file model is suitable for single data set problems, while the latter one can be used for complex models and dynamic data set problems.
Gusek offers support for the development of MPS and CPLEX LP models and empowers you to edit data, perform checks, run the files, and perform conversions between the aforementioned file formats.

Final verdict

All in all, Gusek comprises an advanced set of features under its IDE’s hood for helping you develop new applications, and is suitable especially for professional users.
