Source code for my Master's dissertation entitled Algorithm Selection for Subgraph Isomorphism Problems: A Reinforcement Learning Approach.

Running the scripts

To start, download and install R (version 3.4.4+) from CRAN. This installation contains the R interpreter and a simple GUI app for creating R scripts. This is sufficient to run the scripts in this repo; however, if you are planning to debug or modify the scripts, I highly suggest to use a full-featured IDE like RStudio.

Installing prerequisite packages

Run source('install_packages.R') on R command line to install all the necessary packages.

Rendering R Markdown (.Rmd) files

The rendered contents of the .Rmd files can be readily viewed at RPubs. Check out the following links:

These files can be rendered locally, and the easiest way to do this is through RStudio. Check out this guide.

Dissertation paper

The paper was written in LaTeX using TeXStudio software on Windows. Typesetting files are taken from utmthesis (v5.1) GitHub repository.
