Hi, I am sorry If I was not clear to you early. I was just letting you know of the areas you can work on. The PR refers to a "Pull Request". Are you familiar with github? If not have a look at the following link.
https://help.github.com/articles/using-pull-requests The link of the Pull request I gave to you is an attempt to make the solutions to linear diophantine equation complete. Read the associated paper I have linked to it on top of the Pull request. To solve linear equations completely We need to implement the algorithm given in that paper. What we currently have now is a method I came up during the last summer. Please note that this is not a bug fix, this is a complete re-implemetation of the solutions for linear equations. The two issues I pointed out are improvements suggested by Ondrej. Of course they are not linear equations. You can work on them If you like. You will have to find good references to work on those. There are a lot of references in my blog. http://thilinaatsympy.wordpress.com/ Also search for diophantine equations in the following site. It will give you various types of equations you can work on. http://www.numbertheory.org/ Hope I have made myself clear to you. If not please do ask again.
