Sometimes in a weak moment we ho our code out for bread, butter and tight deadlines. In this flurry, we may have missed a step in the object memory cleanup dance¹. When one thinks they may have sprung an object memory leak, they can turn to the aid of Devel::LeakGuard::Object. It builds upon the admirable Devel::Leak::Object by providing more control over the leak report.

That's being said let's get down and dirty with an example.

The Simplex method was developed in 1947² by George Dantzig when programs referred to (military) strategies. It is a method for finding an optimal solution to a certain problem type called a Linear Program (LP). An optimal solution to an LP does not always exists, but when it does the Simplex method can find it³. This little scrap of a paper introduces an implementation of the Simplex algorithm using Perl. We will use an example to drive the plot.
