As an example, we suppose that we have a set of affine functions \(f_i({\bf x}) = a_i + {\bf b}_i^\top {\bf x}\), and we want to make all of them as small as possible, that is to say, to minimize their maximum. You can begin learning Python and using PuLP by looking at the content below. This is the maximum flow problem. We found it very interesting because Pulp works entirely within the syntax and idioms of Python and provides Python objects that represent problems of optimization and decision variables also allowing constraints to be expressed in a way that is very similar to the original mathematical model. Python turtles can be very good at following instructions. From the Octave website:. PuLP is an LP modeler written in Python.
